Radicals, TRIR spectroscopy

In 1991, Ingold, Lusztyk, and co-workers reported the first direct detection of a transient organic free radical in solution by TRIR spectroscopy [69a], They... [Pg.54]

Turro, George, and co-workers [70] have also observed and studied an acyl radical in solution by TRIR methods in their investigation of the photochemistry of (2,4,6-trimethylbenzoyl)diphenylphosphine oxide (Scheme 2.4). More recently, Vasenkov and Frei [71, 72] reported the generation of the acetyl radical by photolysis of 1-naphthyl acetate (Scheme 2.5) or pinacolone (Scheme 2.2 R = Me, R = f-Bu) in zeolite NaY. Through the use of step-scan FTIR spectroscopy, they observed a carbonyl stretching mode at 2125 cm , interestingly... [Pg.55]
