Hydrophosphination with a commercially available ruthenium compound, bis(cyclopentadienylruthenium dicarbonyl) dimer ([CpRu(CO) 2 ] 2 ), was explored. Styrene derivatives or Michael acceptors react readily with either primary or secondary phosphines in the presence of 0.1 mol % of [CpRu(CO) 2 ] 2 under photolysis with an inexpensive and commercially available UV/A 9 W lamp. In comparison to related photoactivated hydrophosphination reactions with [CpFe(CO) 2 ] 2 as a catalyst, these ruthenium‐catalyzed reactions proceed at greater relative rates with lower catalyst loadings.
