SPECTROSCOPIC INVESTIGATION OF MOLECULAR ASSOCIATION AND PHOTOCHEMICAL REACTION PROCESSES IN ARYL ETHYLENES AND SOME OTHER COMPOUNDS.

An attempt to clarify the conditions under which association of aryl ethylene molecules occurs is described.

Vinylation of aryl bromides using an inexpensive vinylpolysiloxane

(Chemical Equation Presented) A mild and general method for the palladium-catalyzed vinylation of aryl bromides has been developed. The use of tetrabutylammonium fluoride (TBAF) as the activator and an inexpensive and nontoxic vinyl donor, 1,3,5,7-tetramethyl-1,3,5,7-tetravinylcyclotetrasiloxane (D4V, 1), allows for a general and high-yielding preparation of substituted styrenes.

Kinetic Isotope Effects as Probes of the Mechanism of Reaction of 1-Naphthylcarbene with Cyclohexane and Toluene

The rates of reaction of 1-naphthylcarbene (1-NC) in hydrocarbon solution have been measured with excimer laser flash photolysis of 1-naphthyldiazomethane.The kinetic data were obtained by monitoring the growth of the 1-naphthylmethyl radical (1-NCH) at 370 nm.The observed kinetic deuterium isotope effect for the reaction of 1-NC with cyclohexane (cyclohexane-d12) in 2,2,4-trimethylpentane (kH/kD = 1,32 +/- 0.17) and the high CH insertion to H-atom abstraction product ratio are consistent with largely singlet reactivity for 1-NC.In toluene, where addition to the aromatic ring is favored over hydrogen atom abstraction, the measured inverse isotope effect (kH/kD = 0.52 +/- 0.05) also argues for predominantly singlet reactivity and a small singlet-triplet energy gap.The Arrhenius activation parameters measured for the reaction of NC with cyclohexane and toluene were Eact = 2.43 +/- 0.19 kcal/mol, log (A, s-1) = 7.70 +/- 0.15 and Eact = 1.93 +/- 0.38 kcal/mol, log (A, s-1) = 7.28 +/- 0.30, respectively.
