PATENT CLAIMS Process for prepn an alpha-arylated or - vinylated carbonyl compd, comprising
- Reacting compd having carbonyl group & an atom alpha
to carbonyl group bearing at least one H atom with an aryla
ting or vinylating compd selected from: ketone, amides,
esters, carboxylic acids, thioesters, amidines, anhydrides
beta-dicarbonyl compds, alpha-dicarbonyl compds, malo
nitriles, compds with CO groups beta- to sulfoxides, sulfone
phosphates, phosphate esters, & nitriles in the presence of
a base &
- Transition metal catalyst of formula: (X)nM[E(R)1-4]m
X = optional ligand; M = group 8 transition metal, E = ele
ment bearing a nonbonding electron pair when E is not bon
ded to the metal, & R is a substituent bonded to E through
a C, N, O or S atom, with the proviso that R3 cannot contain
3 aryl groups, n = 0-4 & m = 1-4
