Title: The structures of alkenyl- and allyl-magnesium intermediates in the self-hydrogenation of prpyne and allene of magnesium films
Abstract: The structures of the C3H5Mg intermediates formed in the reactions of propyne and allene on magnesium films were determined by converting them into propene-d1 compounds, which were analyazed by microwave spectrometry. Propyne gives mainly the (É)-n-propenyl intermediate. Allene, although largely isomerized to propyned before reaction, gives both allyl and 2-propenyl intermediates, with the first slightly predominant. The formation of these intermediates is assumed to involve hydrometalation of propyne and allene by magnesium hydride.
