Abstract
Abstract: Laser flash photolysis (LFP) of 3-benzyl-3-chlorodiazirine, 1, in isooctane, produces benzylchlorocarbene which reacts with pyridine to form an ylide or undergoes 1, 2- H migration to form the (Z)- and (E)-8-chlorostyrenes. The rate for the 1, 2-H migration is determined by plotting the pseudo-first-order rate constants for the growth of the ylide vs [pyridine] and extrapolating to [pyridine]= 0. From such measurements, performed at ...
