Abstract
The monodentate and bidentate pyridyl phosphines, PR3 and R2P(CH2)(2)P R2, where R = 3- or 4-pyridyl can be prepared in high yields by treatm ent of butyllithium/TMEDA/3- or 4-bromopyridine with PCl3 or Cl2P(CH2) (2)PCl2 at low temperature. 1,2-Bis(di-2-pyridylphosphino)ethane is co nveniently synthesised by an alternative route involving reaction of 1 ,2-dibromoethane with lithium di-2-pyridylphosphide.
