( Department of Chemistry, Texas A&M University, College Station, TX 77843, USA). Inorganic Chemistry, 40(26), 6543-6544 (English) 2001 American Chemical Society. CODEN: INOCAJ. ISSN: 0020-1669. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 35, 75 The syntheses and structures of heterometallic derivs. of zinc and iron contg. bridging cyano groups are reported. Thus, [K][CpFe(CN)2CO] with ZnCl2 gave [Zn][CpFe(CN)2CO]2. To synthesized a more tractable deriv., ZnI2 was reacted with [K][CpFe(CN)2PPh3] which afforded [CpFe(PPh3)(m-CN)2ZnI(CH3CN)]2. Finally, reaction of ZnI2 with [KCpFe(CN)2PPh2(CH2)1.5]2, obtained photochem. from [K][CpFe(CN)2CO] and 0.5 equiv. of dppp, gave {[CpFe(m-CN)2ZnI(THF)]2-m-dppp}, (I). Complex I was characterized by x-ray crystallog. Using complex I as a catalyst for the copolymn. of CO2 and cyclohexene oxide resulted in the prodn. of the cis cyclic carbonate, cis-7-9-dioxabicyclo[4.3.0]nonan-8-one.

DOCUMENT TYPE: Journal CA Section: 78 (Inorganic Chemicals and Reactions) From the reaction of ZnI2 with LiAlH4 in a 3:7 (vol.) Et2O-toluene solvent at variable ratios and concns. of ZnI2 and LiAlH4, temp., and reaction time, ZnH2.nEt2O (n = 0.1-0.3) was obtained. ZnH2.nEt2O was characterized by x-ray diffraction, IR spectra, and thermal anal. methods. .
