sonochemistry for the controlled initiation of radical chain reactions: radicals generated undergo chain reactions in the bulk medium in such a way that the low concentration of the initial radical species may be compensated by the length of the chain. We report here the first synthetic application of this concept by describing hydrostannation and tinhydride reduction initiated by sonochemical thermolysis of
我们已经研究了用于受控引发自由基链反应的均相声化学:产生的自由基在大量介质中进行链反应,初始自由基物种的低浓度可以通过链的长度来补偿。我们通过描述由 R 3 SnH 的声化学热解引发的氢化锡化和氢化锡还原,在这里报告了这一概念的首次合成应用

cyclopropenone acetals with trialkyltinhydride takes place smoothly under radical conditions to afford a variety of 2-alkyl-3-stannylcyclopropanone acetals in high yield. Comparison of the cyclopropene with acetylenes with the aid of inter- and intramolecular competitive experiments revealed the kinetically controlled nature of the reaction of the cyclopropene reaction.
