Abstract

Treatment of the resulting lithio compound with ally1 chloride did not lead (slightly in contrast with one of Padua's results) to the expected product. but instead to ally1 phenyl sulfide (20% isolated yield). The alkylation was houever perfectly performed using ally1 bromide and adding first HHPT~,~(2 equ.). Enones gave only the 1.4-addition products under these conditions (table I)!
