Picosecond radical kinetics. Rate constants for ring openings of (2-alkoxy-3-phenylcyclopropyl)methyl radicals

Rate constants for ring openings of the (trans,trans-2-methoxy-3-phenylcyclopropyl)methyl radical (1M) and the (trans,trans-2-tert-butoxy-3-phenylcyclopropyl)methyl radical (1B) have been determined between -21 and 37 deg C by indirect kinetics employing benzeneselenol trapping as the composition reaction.Radicals 1 were formed in chain reactions of the appropriate 'PTOC esters', 2-thioxopyridine-N-oxy derivatives of the corresponding carboxylic acids, the syntheses of which are reported.Radicals 1 rearrange with rate constants of 8 * 1011 s-1 (1M) and 5 * 1011 s-1 (1B) at 25 deg C with predominant (160:1 and 60:1, respectively) cleavage to give benzylic radical products.The rate constants for ring openings to the minor, alkoxy-substituted radical products represent the first measurements of the kinetic effects of alkoxy substitution on cyclopropylcarbinyl radical ring openings.Precursors to radicals 1 can be employed in mechanistic probe studies that permit differentiation between radical and cationic intermediates.

Photochemistry of Arylbutadienes. Part 2. Preparation and Photochemistry of 1-(Substituted-aryl)butadienes. A Ground-state Substituent Effect on an Excited-state Reaction

Yields and quantum yields are reported for the photoaddition of methanol to 1-phenylbutadiene and eight substituted 1-phenylbutadienes.For allyl and homoallyl products log Φ correlates more satisfactorily with ground-state substituent constants than with excited-state constants; for cyclopropylmethyl products, no correlation is observed with either set of constants.
