Pattacini R, Jie S, Braunstein P: Facile dichloromethane activation and phosphine methylation. Chem Commun. 2009 Feb 28;(8):890-2. Epub 2009 Jan 20.
Isolation of unprecedented zwitterionic organozinc and organocobalt intermediates.. Both C-Cl bonds of CH (2) Cl (2) are readily activated by CoCl (2) and metallic Zn allowing quantitative methylation of phosphines; unprecedented zwitterionic Co (ii) and Zn (ii) intermediates have been characterized which display alpha-metallated phosphoniums. |
