Rezumat:

Peterson olefination of aldehydes and ketones RR1CO (R = H, Me, Et, Ph; R1 = aryl) with BtC-(OMe)SiMe3 (Bt = benzotrazol-1-yl) afforded 1-(benzotriazol-1-yl)-1-methoxy-1-alkenes which were treated without isolation with ZnBr2 and HCl, to yield the corresponding one-carbon homologated carboxylates RR1CHCO2H in good overall yields.
