| Abstract: | The photolysis of a series of gem-dimethyl 4-carbomethoxy 3H-pyrazoles, obtained from a ummon carbanionic precursor (preceding articals) leads to Cyclopropenic esters.These can be hydrogenated to the corresponding cis-disubstituted cyclopropanes which are direct precursors of chrysanthemates, pyrethric esters and analogous halopyrethroids. |
