Acid-catalyzedrearrangement of 6-phenylbicyclo[3.2.0]heptan-6-ol gave 1,1′-biphenyl and 1,1′-biphenyl-carbaldehydes in small amounts as well as the expected rearrangement products. A detailed study of the reaction mechanism revealed that the conversion occurs via an oxidative process through the consecutive formation of cycloheptadienes, cycloheptatrienes, and 1,1′-biphenyls. The acid-catalyzed rearrangement

A study of the effect of phenyl-substitution on the rate of reaction and products produced in the acetolysis of bicyclo[n,1,0]alkyl chlorides provides evidence for three different modes of ring-opening in the transformation of the cyclopropyl to allyl system.

Reaction of 1-phenylcyclooctene and 1-phenylcycloheptene with N-bromosuccinimide (NBS) in aqueous DMSO gives the corresponding 3-bromo-2-phenylcycloalkenes and 2-phenylcycloalk-2-enols in a ratio of 3 : 1. Unlike them, 1-phenylcyclohexene gives a mixture of 3-bromo-2-phenylcyclohexene and 2-bromo-l-phenylcyclohexanol. The oxidation of allylic alcohols with pyridinium chlorochromate afforded the corresponding

Sonochemical reductive silylation of 1-R-7,7-dibromonorcaranes (R = H, Me, Et, i-Pr) by magnesium produces in each case two 7-bromo-7-trialkylsilylnorcaranes (alkyl = methyl or ethyl). The major isomer is exo (the trialkylsilyl group is cis to the R substituent), but the stereoselectivity of silylation decreases as the alkyl group size at C-l increases, 1-Phenyl-7,7-dibromonorcarane produced a mixture of phenylcycloheptadienes and monobromonorcaranes.
