                                Stable organozinc compounds derived from alkyl 3-alkyl 2-(bromomethyl) propenoates reacted with ketones and aldehydes to give alpha-methylene gamma-butyrolactones in excellent yields.  Different reaction parameters were studied and some transition states were proposed.
