Selective Synthesis of Carbonyl Olefinating or Alkylating Reagents from MoCl₅ and MeLi by Changing the Solvent or the Rate of Addition of MeLi

Abstract

The simple change from rapid to slow admixture of the educts is decisive in determining whether carbonyl olefinating reagents (1, 2) + CH4 or carbonyl alkylating reagents (3, 4) + ethane are formed from MoCl5 and MeLi in tetrahydrofuran.
