ABSTRACT:
Preparation of tert-(cyclo)alkyl 1-hydrogen-2- hydrocarbylcyclopropanecarboxylates or 1-tert-(cyclo)alkyl spiro [2,p] alkanecarboxylates where p is an integer of at least 2 by reaction of a tert-(cyclo)alkyl 1-hydrogen-2-halocyclopropanecarboxylate with a (1) hydrocarbylmagnesium halide or (2) polymethylene-bis(magnesium halide)- or a magnesiacycloalkane, followed by addition of a proton donor to the reaction product thus obtained.
