Dinuclear μ-oxo osmium porphyrins containing terminal OsCPh2 bonds with a linear COs–O–OsC moiety were prepared, which are reactive toward pyridine to form [Os(Por)(CPh2)(py)] and are active catalysts for inter- and intra-molecular cyclopropanation of alkenes and for carbene insertion into saturated C–H bonds.
