Insecticidally active vinyl-cyclopropane carboxylic acid esters of the formula ##STR1## are prepared by reacting ##STR2## in which R.sup.12 is a radical selected from the group consisting of ##STR3## with an alcoholate of the formula M--O--R.sup.8. Various processes for making the intermediates are also described. Many of the intermediates and end products are new.
