摘要:
Alpha substituted alkylarylketals of formula: ##STR1## wherein Ar is an aromatic radical having from 3 to 20 C atoms,X is halogen, OR.sub.3 (wherein R.sub.3 is H, acyl or aroyl), OSO.sub.2 CH.sub.3 or OSO.sub.2 C.sub.6 H.sub.4 --CH.sub.3,R is H or alkyl having from 1 to 3 C atoms,Y is --CH.sub.2 --C(R.sub.1).dbd.C(R.sub.2)--CH.sub.2 --(wherein, in turn, R.sub.1 and R.sub.2 are H or methyl).The products of formula I are useful for preparing alpha-aryl-alkanoic acids.
