Abstract
Rate constants for the pyrolysis of the indenyl diazo compounds, 5 a-5 e, in methanol have been determined and correlated with σ+, giving a ρ+=-0.76. The product of this pyrolysis reaction is the methyl ether resulting from trapping at the carbenic centre. The mechanism proposed for this process involves rate-determining unimolecular loss of nitrogen by the allowed nonlinear pathway to form the singlet σ2 carbene. Evidence presented implies ...
