Reaction of singlet molecular oxygen with tetramethyl- o-xylylene

We describe here the evaluation of the rate constant of reaction of singlet molecular oxygen with tetramethyl- o-xylylene, an intermediate in the photolysis of 1,1,3,3-tetramethyl- 2-indanone. This is a rare example of quantitative analysis of transient-transient reaction kinetics between two differ...

Description
Summary:We describe here the evaluation of the rate constant of reaction of singlet molecular oxygen with tetramethyl- o-xylylene, an intermediate in the photolysis of 1,1,3,3-tetramethyl- 2-indanone. This is a rare example of quantitative analysis of transient-transient reaction kinetics between two different intermediates; the rate constant, 3.2 × 10 8 M −1 s −1, demonstrates the efficient nature of the reaction.
