  Reactions of alkene or alkyne with diphenylphosphine and catalytic [κ5‐N,N,N,N,C‐(Me3SiNCH2CH2)2NCH2CH2NSiMe2CH2]Zr (1) are greatly enhanced under photolysis, providing viable catalytic hydrophosphination with a broad substrate scope. Whereas diphenylphosphine had been an inaccessible substrate under thermal conditions, complete conversion of alkene substrates to tertiary phosphine is achieved in as
