Photolysis of benzaldehyde in solution: the products
Abstract
Benzaldehyde when irradiated in benzene yielded almost equal amounts of benzoin (I), deoxybenzoin (II), and 1,2-diphenylethane-1,2-diol (III); in ethanol the main product was (III) with only a trace of (I); while in hex-1-yne, seven isolable products were (I), (II), (III), heptanophenone (IV), cis-hept-2-eno-phenone (V), trans-hept-2-enophenone (VI), and 2-n-butyl-1,4-diphenylbutane-1,4-dione (VII).
