Dodecyltrichlorosilane is a colorless to yellow liquid with a pungent odor. It will burn though it may take some effort to ignite. It is decomposed by moisture or water to hydrochloric acid with evolution of heat. It is corrosive to metals and tissue.
The silanes decomp at elevated temp to liberate hydrogen and deposit a high purity silicon, which leads to some of the principal uses of silanes. /Silanes/
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Silane, Chlorosilane, and Related Compounds/
Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary ... . Anticipate seizures and treat if necessary ... . Monitor for shock and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with 0.9% saline (NS) during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal (refer to ingestion protocol in Section Three ... . Cover skin burns with sterile dressings after decontamination ... . /Silane, Chlorosilane, and Related Compounds/
Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious, has severe pulmonary edema, or is in severe respiratory distress. Early intubation at the first sign of upper airway obstruction may be necessary. Positive-pressure ventilation techniques with a bag-valve-mask device may be beneficial. Consider drug therapy for pulmonary edema ... . Monitor cardiac rhythm and treat arrhythmias if necessary ... . Start IV administration of D5W /SRP: "To keep open", minimal flow rate/. Use 0.9% saline (NS) or lactated Ringer's (LR) if signs of hypovolemia are present. For hypotension with signs of hypovolemia, administer fluid cautiously. Consider vasopressors if patient is hypotensive with a normal fluid volume. Watch for signs of fluid overload ... . Treat seizures with diazepam or lorazepam ... . Use proparacaine hydrochloride to assist eye irrigation ... . /Silane, Chlorosilane, and related compounds/
/SIGNS AND SYMPTOMS/ Acute inhalation exposure may result in sneezing, choking, laryngitis, dyspnea (shortness of breath), respiratory tract irritation, and chest pain. Higher exposure can cause pulmonary edema, a medical emergency that can be delayed for several hours. This can cause death. Bleeding of nose and gums, ulceration of the nasal and oral mucosa, pulmonary edema, chronic bronchitis, and pneumonia may also occur. If the eyes have come in contact with dimethyldichlorosilane, irritation, pain, swelling, corneal erosion, and blindness may result. Dermatitis (red, inflamed skin), severe burns, pain, and shock generally follow dermal exposure. Inhalation irritates mucous membranes. Severe gastrointestinal damage may occur. Vapors cause severe eye and lung injury. Upon short contact, second and third degree burns may occur. Signs and symptoms of acute ingestion of dimethyldichlorosilane may be severe and include increased salivation, intense thirst, difficulty swallowing, chills, pain, and shock. Oral, esophageal, and stomach burns are common. /Dimethyldichlorosilane/
伯烷基硅烷（RSiH 3，其中R = n -C 12 H 25或n -C 8 H 17）在（Ph 3 P）3 RhCl（1）的存在下进行脱氢偶联，得到低聚产物。29 Si { 1 H} -NMR和凝胶渗透色谱表明，在这些反应中最多形成5-6个硅链。推测这两种底物具有可比的SiH反应性，观察到的产物分布变化可能与氢气从反应混合物中的相对离开速率有关。该系统对H的敏感性2（g）浓度可能最终允许控制所形成的特定链长。
The first example of a hypervalent iodine(III)‐mediated oxidativefluorination of alkylsilanes by fluorideions without the use of transition metals is demonstrated. This reaction is operationally simple, scalable, and proceeds under mild reaction conditions. Mechanistic studies suggest the involvement of a single‐electron transfer resulting from the interaction of an organopentafluorosilicate and
Alcohol‐free: A versatile, efficient, and practical synthesis of alkoxysilanes without generation of HCl involves the reaction of chlorosilanes with unsymmetrical ethers in the presence of a Lewis acid (see scheme). The reaction proceeds through selective cleavage of CO bonds and is superior to conventional processes. Industrially feasible reagents are used and only one by‐product results.

A series of silafluorene-based copolymers, poly[9-(2-ethylhexyl)-9-dodecyl-silafluorene-2,7-diyl-alt-5,5-(4′,7′-di-2- thienyl-2′,1′,3′-benzothiadiazole)] (P1), poly[9-(2-ethylhexyl)-9-dodecyl-silafluorene-2, 7-diyl-alt-2,5-bis-(thiophene-2-yl)thiazolo [5,4-d]thiazole] (P2), and poly[9-(2-ethylhexyl)-9-dodecyl-silafluorene- 2,7-diyl-alt-5,5-(5′,8′-di-2-thienyl-2,3-bis(4-octyloxyl)phenyl)quinoxaline] (P3), were synthesized and used as donor materials in polymer solar cells (PSCs). The optical, electrochemical, and photovoltaic properties of the copolymers were investigated. The results indicate that the acceptor units in the copolymers influenced the band gap, electronic energy levels, and photovoltaic properties of the copolymers significantly. The band gaps of the copolymers were in the range 1.82–2.10 eV. Under optimized conditions, the silafluorene-based polymers showed power conversion efficiencies (PCEs) for the PSCs in the range 1.31–1.69% under AM 1.5 illumination (100 mW/cm2). Among the three copolymers, P1, which contained a benzothiadiazole acceptor unit, showed a power conversion efficiency of 1.69% with a short circuit current of 4.59 mA/cm2, open circuit voltage of 0.88 V, and a fill factor of 0.42, under AM 1.5 illumination (100 mW/cm2).
