A process for producing a secondary phosphine of formula (2) wherein R1 and R2 may be the same or different and each represent an alkyl group, a cycloalkyl group or an aryl group, each of the above groups being optionally substituted by an alkyl group, an alkoxy group, a halogen atom, a perfluoroalkyl group, an amino group or a phosphino group, which comprises reacting a phosphine halide of formula (1) wherein R1 and R2 are as defined above and X represents a halogen atom, with a metal selected from the metals of Groups 2 to 15 in the Periodic Table or an alloy thereof and reacting the resultant metal di-substituted phosphide with an agent for protonation.
