7-Methyl-trans-bicyclo[4.1.0]hept-3-ene has been synthesized and the thermal and transition-metal-complex promoted rearrangements of trans-bicyclo[4.1.0]hept-3-ene, 7-methyl-trans-bicyclo[4.1.0]hept-3-ene, and 7,7-dimethyl-trans-bicyclo[4.1.0]hept-3-ene have been compared.

acceptor character of the phosphorus ligand, and a relationship between Os−P bondlengths and coupling constants was found. Osmium relaxation rates T1-1 and their B0 field dependence are reported for selected complexes. The crystalstructures of four Os(p-cymene)Cl2L complexes (L = PMe3 (1), P(OMe)3 (6), PBz3 (13), and PPh3 (15)) have been determined.
