Differentiation of the reactivities of carbon-carbon multiple bonds in one molecule. Highly chemo- and stereo-selective hydrohalogenation of allyl or propargyl propiolates
摘要:
The reaction of allyl or propargyl propiolates with lithium halides in acetic acid afforded allyl or propargyl (Z)-3-halopropenoates highly chemo- and stereo-selectively by differentiation of reactivities of carbon-carbon multiple bonds in the same molecule.
