Regioand stereoselective photoallylation of electron-deficient alkenes by use of allylic silanes via photoinduced electron transfer has been described. Similar photoinduced functionalization reactions such as arylmethylation, alkylation, and silylation can be achieved by using a variety of organosilicon compounds. These photoreactions proceed via radical cations of organosilicon compounds and r...
A number of organosilicon and organogermanium derivatives and some related compounds including the N-substituted. 2-[1-naphthylmethyl]-2-imidazoline and 2-[1-(1-naphthyl)ethyl]-2-imidazoline have been prepared and the toxicity of some compounds have been determined in mice. In this paper we report the synthesis and the evaluation of the pharmacological activity of new organosilicon and organoge...
Metal-free deprotonative functionalization of heteroaromatic compounds was achieved using an organic superbase catalyst; an organosilicon additive such as trimethylsilylpropyne was employed for activating the catalytic cycle of 1,2-addition to carbonyl compounds.
The present review describes the work carried out during the last 20 years in the field of the radioprotective activity and toxicity of several classes of organosilicon and organogermanium compounds (i.e. metallathiazolidines, metalladithioacetals, metallatranes and germathianes).
The indium triiodide catalyzed single-stage cascade reaction of N-sulfonyl amides with hydrosilanes and two types of organosilicon nucleophiles such as silyl cyanide and silyl enolates selectively promoted deoxygenative functionalization to give α-cyanoamines and β-aminocarbonyl compounds, respectively.
