Lj. Zhang et Yz. Huang, ON TERTIARY STIBINE .1. REACTION OF OMEGA-BROMOACETOPHENONE WITH ALDEHYDES MEDIATED BY DIPHENYLANTIMONYORGANOMETALLIC REAGENTS, Journal of organometallic chemistry, 454(1-2), 1993, pp. 101-103
In the presence of diphenylantimonymagnesium, various aldehydes react
readily with omega-bromoacetophenone to form alpha,beta-unsaturated ke
tones in good yields.
