✦ Synopsis

The recent publication by Yang and Loeechen (1) on the photochemical reaction of 9-anthraldehyde uith 2,3-dimsthyl-2-butene proapt u8 to report our finding8 on this and other systems involring 9-anthraldehyde. We have studied the photo-reaction of 9-8nthraldehyde uith 2,3_dimethyI-2-butene under eqerimental condition8 (A = 36600A, temp. = 30-35O) which differ from tho8e of Yang et al. ( ). whereas Yang (3) ha8 foundthatthe oxetane I ua8 the major product of the reaction nhen light of uavelength shorter than 400 sp via8 oeed, ue bare fonad that under our condition8 the pinacol II end polywric material are the major product8 of the reaction and thatoxetane I and al80
