In this video we have seen generation of ketene and the modes of cycloaddition of ketene to alkenes.We have seen that 2+2 cycloaddition of ketene with alkene is thermally allowed , the reaction is Suprafacial- antarafacial and it occurs through the perpendicular approach of the two components.Suprafacial component is alkene and antarafacial component is ketene.Then we have seen the Regioselectivity and stereoselectivity .We have also seen that ketene does not give 4+2 cycloaddition with diene instead it gives 2+2 cycloaddition with diene.This video is helpful for Msc chemistry students and also for those who are preparing for different competitive exams related to chemistry.
