Abstract

Preparative-scale photolyses of the title triisopropylphenyl-substituted compounds 1 and 4 at 254 nm, in the presence of alcohols, led to aryl-H-phosphinates 3 in good yields. Reaction of the tri-tertbutylphenyl derivative 5 was, however, accompanied by side reactions. The results of two series of competitive reactions are consistent with a mechanism involving a five-coordinate adduct 8 of the alcohol on the P = O group of the phosphanorbornene oxides.
