Abstract

Abstract: Transients assigned as o-xylylenes have been observed in the flash photolysis of a series of methylated 2-indanones. Thus, 1, I, 3, 3-tetramethyl-2-indanone gives a transient, assigned as 7, 7, 8, 8-tetramethyl-o-xylylene (absorption maximum at 350 nm), while l, l- dimethyl-2-indanone gives a transient with absorption maximum at 360 nm, assigned as 7, 7- dimethyl-oxylylene. Both these transients decay (thermally and photochemically) by a 1, 5- ...
