“…Interestingly, the nonequivalence of the isopropyl groups in the solid state cannot be observed in solution. The 13 C NMR spectra in benzene-D 6 display one signal for carbonyl and also one signal for both isopropyl groups, indicating a high fluxionality in 4 on the NMR time scale, similar to that observed 2 and analogous Ni(CO) 2 (L) 2 complexes [42,43]. The IR showed two characteristic stretching signals at 2039 (A 1 ) and 1,967 cm -1 (B 1 ), confirming that GaL is a ligand with good r-donor and poor p-acceptor qualities.…”

“…Reactions of GaL with Ni(CO) 4 : Synthesis and Structure of Ni(CO) 3 (GaL) (3) and Ni(CO) 2 (GaL) 2 (4) Reaction of GaL with Ni(CO) 4 at room temperature in benzene or hexane led to an immediate evolution of CO and formation of the nickel complex Ni(CO) 3 Ni ( [42,43]. To unambiguously characterize this compound single crystals were grown for an X-ray diffraction analysis.…”

“…40,41 Exposure of unsaturated silylene 16 to Ni(CO) 4 resulted in the formation of the disilylene-substituted tetrahedral nickel complex 17 (Scheme 7.3). 42,43 Similarly, mixing Ph 3 PAuCl with decamethylsilicocene 18 produced the silylgold complex 19. 44 The 29 Si { 1 H} NMR spectrum of 19 (d 78 ppm) revealed its silylenoid character.…”

“…Chemical species which involve divalent silicon atoms, silylenes, are key intermediates in numerous thermal and photochemical reactions of organosilicon compounds [4]. Besides, much interest has been focused on their bonding properties and reactivities such as addition to olefins [11,12], alkynes [13], isocyanides [14], and transition metal complexes [15] in connection with the reactivities of carbenes. The multiple-bond compounds including second period elements such as olefin, imine (Schiff base), ketone, acetylene, nitrile, etc.…”
