Procedure
Alternatively, a vinyl phenyl hydroxyflavone may be prepared by synthesizing 4-styrene trimethyltin and combining it with 4-bromobenzaldehyde to produce 4'-vinyl, 4-biphenyl aldehyde. This intermediate compound is then reacted with 2-hydroxyacetophenone to produce the vinyl phenyl hydroxyflavone. This reaction scheme proceeds as follows: ##STR10##
