โœฆ Synopsis

Benzene when photochemically excited undergoes cycloadditions to alkenes in a 1,2-,1,3-, and 1,4-manners although the 1,3-addition is favoured on orbital symmetry grounds, 1,2,3 whereas the photochemical additions between benzene and various acetylenes take place solely in the 1,2-fashion. 435 However, it has been shown that the excited species in this case is the acetylene rather than the benzene.

Photochemical additions of benzene to alkenes have been a subject of current interest, 1,2,3 but only preliminary investigations have been reported on the corresponding reactions with 1,3dienes.4 graft and Koltzenberg found that benzene reacted photochemically with 1,3-butadiene and isoprene to give

Cyclohexenones I were allowed to react with allyltrimethylsilane and three allyltributylstannanes in the presence of titanium tetrachloride. Products 2 and 2 were formed in ratios ranging from 7:l to 26:l (2:3). Ratios resulting from the use of other Lewis acids -support 4 as an intermediate which a
