Nitrogen Donor Ancillaries

9 Nitrogen Donor Ancillaries. - The reaction of the salt di-K-l,3-di(2-(NPF2)troponiminate)-propane, K2[(PF)TP], with LuCb leads to [[(PF)TP] 

10 Other Andllaries. - A review of lanthanide hydrides with a focus on the hydride function, uncoordinated and metallic hydrides and their use as catalysts in diene polymerization has appeared. Steric and electronic effects on the stability of early lanthanide, neodymium and samarium, organometallic hydrides are discussed.  

In a very stimulating work, the molecular hydrides LnH2(THF)2 (Ln = Sm or Eu) were prepared by hydrogenolysis of the naphthalene complexes of divalent samarium and europium, CioH8Ln(THF)2 (Ln = Sm or Eu), and of the stilbene compound of samarium(II), (PhCHCHPh)Sm(DME)2, in THF. The resulting complexes were characterized by conventional spectroscopic techniques. Both hydrides will polymerize styrene but are inactive toward propylene. The reac-

A series of zerovalent molybdenum and tungsten SO2 complexes containing carbonyl and nitrogen donor (bipy, phen, py) ancillary ligands was reported to possess unusually low v(SO) values (873-935 cm ) Levison correctly suggested, long before the first struc-... 

Platinum(II) species are often known as good electrophiles. However, proper ancillary ligands of nitrogen donors,...
