DOCUMENT TYPE: Journal CA Section: 78 (Inorganic Chemicals and Reactions) Section cross-reference(s): 75 CuLQ (L = dicyclohexyl(2-biphenyl)phosphine (L1), bis(tert-butyl)(2-biphenyl)phosphine; Q = 3,6-di-tert-butyl-o-benzosemiquinolate) were prepd. from Cu chloride, L and TlQ. CuL1Q is monoclinic, space group P21/n, Z = 4, R1 = 0.0525, wR2 = 0.1199. The Cu(I) coordination environment in these complexes is trigonal planar. ESR was used to det. the structure of the complexes in soln.; the trigonal planar structure is retained in soln.Except for chemicals metioned above, 224311-51-7 and 247940-06-3 are also used. .
