Photochemically inudced chelate ring expansion and hydrolysis reactions: X -ray crystal structures of [W{PPh 2 OC(Ph)[double bond, length half m-dash]CHPPh 2 }(CO) 4 ] and [W(PPh 2 OH)(PPh 2 CH 2 COPh)(CO) 4 ] Academic Article uri icon


  • 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.
