摘要

Rapid addition of a tertiary amine to tin(iv) chloride-selenoacetal mixtures leads to the corresponding vinyl selenides in good yield, whereas slow addition of the amine base gives aldol condensation products. ... Selenium-stabilised carbocationic species have proved valu- able electrophiles in carbon-carbon bond-forming reactions. 1 However, carbenium ions bearing heteroatomic substituents on the positively charged carbon may follow other reaction paths, depending ...
