Abstract
A series of alkoxy-containing-alkyl phenylglyoxylates have been synthe sized and their photochemical reactions studied, The intention was to probe structural requirements for remote hydrogen abstraction, Product s resulting from 1,10- and 1,11-hydrogen abstraction were isolated fro m the photochemical reactions of 4'-methoxybutyl phenylglyoxylate 3d a nd 5'-benzyloxypentyl phenylglyoxylate 3h respectively. Products resul ting from Norrish Type II and intermolecular hydrogen abstraction reac tions were also isolated, Triplet lifetimes of representative compound s were measured by laser flash photolysis.
