Abstract

Light of intensity normally found in a laboratory transforms the 4-membered ring chelate [W{PPh₂CH(COPh)PPh₂}(CO)₄] into the 6-membered ring chelate [W{PPh₂OC(Ph)CHPPh₂}(CO)₄] and thence into a hydrolysis product [W(PPh₂OH)(PPh₂CH₂COPh)(CO)₄]; neither reaction occurs in the absence of light.
