Method for manufacturing alkenyl phosphorus compound

A method for manufacturing an alkenyl phosphorus compound by reacting a phosphorus compound represented by the following general formula (1):

• wherein
• R1 and R2 each independently represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted aryloxy group;
• and R1 and R2 may be bonded to each other to form a cyclic structure;
• and an alkynyl compound represented by the following general formula (2):
• wherein
• R3 and R4 each independently represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heteroaryl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, or a substituted or unsubstituted silyl group,
• in the presence of a transition metal complex and a Lewis acid,
• wherein the Lewis acid is at least one metal compound selected from the group consisting of zinc chloride, zinc bromide, and iron (II) chloride, and the amount of Lewis acid is 3 to 30 mol per 1 mol of the transition metal complex,
• wherein the alkenyl phosphorus compound is represented by the following general formula (3):
• wherein, R1 and R2 are synonymous with R1 and R2 in general formula (1), and R3 and R4 are synonymous with R3 and R4 in general formula (2), and
• wherein the conversion of the phosphorus compound to the alkenyl phosphorus compound is 40% or more.
