Biography

Nametkin was born in Kazan and orphaned at an early age. He was educated at a gymnasium in Moscow, after which he earned a living as a private tutor. He studied chemistry and became a lecturer in organic chemistry at the Moscow University but quit in 1911 to oppose the policies of L.A. Kasso. He then studied under N.D. Zelinsky, and received a doctorate in 1917. In 1927 he went to the Moscow Mining Academy and became a director of the Institute of Petroleum in 1948.


Nametkin rearrangement

The Nametkin rearrangement is the shift of a methyl group in this scheme and called the 'Nametkin' step. The shift of the ring bond is actually a standard Wagner-Meerwein shift. The reaction can in fact be used to make the terpene, using chlorocamphene. A museum of petrochemistry was started in 2011 and named after S.S. Nametkin.
