The reaction of silatrane HSi(OCH2CH2)3N with mercury(II) salts HgX2 (X = OCOMe, OCOCF3, OCOCCl3, SCN, Br) afforded the corresponding 1-substituted silatranes XSi(OCH2CH2)3N in good yields.

simple carbonylreductions as borohydrides. Hydrosilane reducing agents broadly fall into one of two general categories: either a) they are easy to handle and require expensive and/or hazardous additives, or b) they are difficult and/or dangerous to handle. This work details the discovery of mild and functional group compatible conditions utilizing hydrosilatrane for the selective reduction of aryl
氢硅烷是廉价、容易获得的底物,但它们在简单羰基还原方面的用途不如硼氢化物广泛。氢硅烷还原剂大致分为两大类之一:a) 它们易于处理并且需要昂贵和/或危险的添加剂,或者 b) 它们难以处理和/或危险。这项工作详细介绍了温和和官能团相容条件的发现,利用氢化硅油将芳基醛选择性还原为苯甲醇,而不会形成不必要的醚或脱氧产物。这种方法在硅烷还原方面取得了重大进展,因为硅丙烷是一种空气和水分稳定但相对反应性的还原剂,可用于台式露天反应。
Aromatic C–H silylation of arenes with 1-hydrosilatrane catalyzed by an iridium(i)/2,9-dimethylphenanthroline (dmphen) complex
Aromatic CâH silylation of neat arenes with 1-hydrosilatrane was found to be efficiently catalyzed by iridium catalysts composed of 1/2[Ir(OMe)(cod)]2 and 2,9-dimethyl-1,10-phenanthroline at 120 °C to afford the corresponding silylated products in high yields. The silylated products can be used for the Hiyama cross-coupling reaction.
Reaction of phenyltrifluorosilane with 1-hydro- and 1-ethoxysilatranes proceeds with the cleavage of the F-Si bond and the formation of 1-fluorosilatrane. Under the action of alkylsilatranes also the cleavage of C-Si bond is observed with the formation of a minor product, 1-fluorosilatrane.

A method of synthesis of 1-silatranyl nitrate O(2)NOSi(OCH(2)CH(2))(3)N based on the reaction of 1-hydrosilatrane with mercury nitrate in the acetonitrile medium was developed. The structure of the synthesized 1-silatranyl nitrate, mp 227A degrees C, was confirmed by elemental analysis, (1)H, (13)C, and (29)Si NMR spectoscopy, infrared spectroscopy, and mass spectrometry. Silatranyl nitrate previously described in the literature as yellowish viscous oil apparently contains impurities preventing its crystallization.
