Participants

Reaction Steps

This example shows the preparation of a phosphine oxide, that is a compound containing three P--C bonds. Warming (50°-100° C) of a mixture of ethyl dimethylphosphinite, acetaldehyde and urea in the presence of a catalytic amount of boron trifluoride etherate gives dimethyl (1-ureidoethyl)phosphine oxide, a product that cannot be hydrolyzed to an acid of phosphorus.
