/SRP:/ 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 if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the 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. /Poisons A and B/
/SRP:/ 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 needed. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary ... .

/LABORATORY ANIMALS: Subchronic or Prechronic Exposure/ Subchronic toxicological effects of 2,4,6-trichlorobenzyl chloride and its oxidative derivative trichlorobenzoic acid were investigated. 2,4,6-Trichlorobenzyl chloride was dissolved in ethanol and added to rat chow on a weekly basis at concentrations of 0, 0.15, and 0.30 percent. Trichlorobenzoic acid was fed in dietary levels of 0, 10, 30, or 100 ppm for 90 days Sprague-Dawley albino rats and beagle dogs. Acute 50% lethal dose in male and female rats was determined to be 3075 mg/kg. In subchronic studies, a marked reduction in weight gain was apparent throughout the study in male and female rats given 3000 ppm 2,4,6-trichlorobenzyl chloride and male rats given 1500 ppm 2,4,6-trichlorobenzyl chloride for 3 weeks. The only microscopic changes noted were hepatic degenerative alterations, prominent in all male and female rats receiving 3000 ppm 2,4,6-trichlorobenzyl chloride. No blood or urine chemistry changes were seen. Rats and dogs receiving 100 ppm 2,4,6-trichlorobenzoic acid for 90 days showed no treatment related effects on survival, growth, food consumption, or behavior. No significant differences were noted in blood or urine parameters in these animals, and no histologic changes were seen. /It was/ concluded that 2,4,6-trichlorobenzyl chloride has lower acute oral toxicity than benzyl halides. 2,4,6-Trichlorobenzyl chloride also appears to be less acutely toxic than its acid derivative, trichlorobenzoic acid. Repeated exposures to 2,4,6-trichlorobenzyl chloride resulted in chemically induced liver injury with marked degenerative/regenerative processes and no excessive accumulation of lipids. /It was suggested/ that 2,4,6-trichlorobenzyl chloride may be metabolized differently from other benzyl halides, perhaps because of its aromatic constituents or differences in solubility which affect uptake or retention.

Carboxylation of C−H Bonds Using <i>N</i>-Heterocyclic Carbene Gold(I) Complexes
作者:Ine I. F. Boogaerts、Steven P. Nolan
DOI:10.1021/ja103429q
日期:2010.7.7
A highly efficient [(NHC)Au(I)]-based (NHC = N-heterocyclic carbene) catalytic system for the carboxylation of aromatic and heteroaromatic C-H bonds was developed. The significant base strength of the Au-OH species is at the origin of the activation process and permits the facile functionalization of C-H bonds without the use of other organometallic reagents.
