Abstract

Fremgangsmåte for fremstilling av a-substi-tuerte alkylarylketaler med formelen. hvori Ar er en aromatisk rest med fra 3 til 20 karbonatomer,. X er halogen, OR(der Rer H, acyl eller aroyl),. OS02CH3 eller OS0CH,. R er H eller alkyl med fra 1 til 3 karbonatomer,. Y er -CH-C(R)=C(R)-CH- (hvori R.] og Rer H eller metyl).Produktene med formel I er brukbare for fremstilling av a-arylalkansyrer.
