(Figure Presented) Primary C-H bond activation! A Rh complex of bis-pocket porphyrin I catalyzes carbenoid insertion into the C-H bonds of n-alkanes with a primary/secondary selectivity (per C-H bond) of up to 11.4:1 (see picture). Enantioselective secondary C-H bond functionalization catalyzed by a Rh complex of Halterman's chiral porphyrin features up to 93% ee. These reactions exhibit up to 6477 turnovers after the catalyst was recycled five times.

Carbethoxycarbene, from ethyl diazoacetate and rhodium(III)porphyrins, inserted into methyl C-H bonds of n-alkenes (C6 to C12) with yields up to 20-25 percent corresponding to a large increase of the primary/secondary selectivity.
