Article abstract of DOI:10.1039/DT9800002428

Interaction of LiR and MCl3 in appropriate stoicheiometry affords the following new compounds: MCl2 or M2Cl (M = P, As, or Sb), MCl2 or M2Cl (M = As or Sb), or Bi3.Reaction of P(NPri2)Cl2 with Li*OEt2, Li, Li, MgButBr, or NHPri2 yields the corresponding new compound P(NPri2)RCl, while Li with P(NMe2)Cl2 affords P(NMe2)Cl.Reduction of the appropriate phosphorus(III) or arsenic(III) monochloride in toluene by photolysis with the olefin gives the persistent (t1/2 = 3 days to > 1 year in PhMe at 300 K) phosphorus(II) or arsenic(II) alkyl or amide: <*>M2 (M = P or As), <*>M2, <*>P(NR2) (R = Pri or SiMe3), <*>P(NPri2),<*>P2, or <*>P(NPri2).Electron spin resonance parameters are discussed.
