Conformational effects on the excited state 1,2-hydrogen migration in alkyldiazomethanes

Excited state rearrangements of alkyldiazo compounds are well-known. In particular, 1,2-hydrogen migrations to give carbene products are common. In this communication we provide evidence showing the migration in the diazo excited state is dependent upon the dihedral angle formed between the migrating hydrogen and the diazo carbon.
