Abstract

Abstract Biphenyl-2-ylcarbenes, 2-ArC 6 H 4 CR, were generated photolytically and thermally from diazo precursors. Cyclization, leading to fluorenes, competes with capture of the carbenes by methanol but proceeds faster than intramolecular hydrogen shifts (with R= Me) and intermolecular C (SINGLE BOND) H insertion reactions (with R= H in cyclohexane). By comparison of product ratios with kinetic data for related carbenes from the literature, ...
