Light of intensity normally found in a laboratory transforms the 4-membered ring chelate [WPPh2CH(COPh)PPh2}(CO)4] into the 6-membered ring chelate [WPPh2OC(Ph)CHPPh2}(CO)4] and thence into a hydrolysis product [W(PPh2OH)(PPh2CH2COPh)(CO)4]; neither reaction occurs in the absence of light.
通常在实验室中使用的强光将4元环螯合物[WPPh2CH(
COPh)PPh2}(CO)4]转化为6元环螯合物[WPPh2OC(Ph)CHPPh2}(CO)4],并进一步转化为
水解产物[W(PPh2OH)(PPh2CH2
COPh)(CO)4];在没有光的情况下,这两种反应都不会发生。
