Photoreaction of triarylstibines with styrenes resulted in the formation of 2-aryl-1-phenylethanols accompanied by air oxidation. Formation of the products has been explained by the valence expansion of the oxygen-antimony- styrene complex to a five-valent intermediate, followed by reductive coupling.
