TP-MeMgCl is ThioPhenyl-MethylMagnesium Chloride, or Chloro(2-thienylmethyl)magnesium.
Molecular Formula
C5H5ClMgS
Timothy: I synthesized TP-MeMgCl by adding magnesium turnings in anhydrous dibutyl ether with ultrasound and reacted it with acetonitrile and hydrolyzed it with hydrochloric acid to yield TP2P (ThioPhenyl-2-Propanone, 2-Thienylacetone).
