HOMOLOGATION OF N-ALKANES USING DIAZOESTERS AND RHODIUM(III)PORPHYRINS. ENHANCED ATTACK ON PRIMARY C-H BONDS.

Article abstract of DOI:10.1016/S0040-4039(00)85590-2

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.
