Ge2R4[having a trans-folded C2h Ge2C4 framework with a fold angle of 32°, a germanium environment intermediate between pyramidal and planar (sum of angles at Ge = 348°) and a GeGe bond length of 2.347(2)Å(ca. 4% shorter than in elemental germanium)], which behaves chemically as a singlet germylene eR2.
by the fact that the hapticity of the ligand in the Ti and Ni substrates changes easily allowing for an extra temporary coordination of [Re2(CO)9], for example, generated in situ and leading to CpRe(CO)3. Heating titanium compound 1 with Re2(CO)10 led to CpRe(CO)3 and the substituted cyclopentadienyltricarbonylrhenium compound 2 with yields of 36 and 37%, respectively.

Cp2(THF)ZrN-t-Bu (1a) toward a series of organic and metal carbonyl complexes has been examined. The ZrN linkage of 1a undergoes imido/oxo exchange reactions with the carbonylcompounds and generates three different types of oxozirconocene products: (Cp2ZrO)n (3), (Cp2Zr)2(μ-O)(μ-N-t-Bu) (9), and (Cp2Zr)2O3CCPh2 (12) were obtained from the reactions of 1a with RR‘CO (R = R‘ = Me (2b); R = Ph, R‘ = H (2c);
已经检查了 Cp2(THF)ZrN-t-Bu (1a) 对一系列有机和金属羰基配合物的反应性。1a 的 ZrN 键与羰基化合物发生亚胺/氧代交换反应并生成三种不同类型的氧代锆茂产物:(Cp2ZrO)n (3)、(Cp2Zr)2(μ-O)(μ-Nt-Bu) (9 ), 和 (Cp2Zr)2O3CCPh2 (12) 是从 1a 与 RR'CO 的反应中获得的 (R = R' = Me (2b); R = Ph, R' = H (2c); R = i-Pr, R' = H (2d))、CpCo(CO)2 (7) 和 Ph2CCO (10)。这些反应中的副产物分别是亚胺 RR'CN-t-Bu (4b-d)、异腈配合物 CpCo(CO)(CN-t-Bu) (8a) 和烯酮亚胺 Ph2CCN-t-Bu (11a)。随着含有α-氢原子的更多受阻羰基,反应遵循不同的途径,导致形成烯醇配合物Cp2Zr(NH-t-Bu)(OCR3CR2R1)

products, (HCCCR1R2CR1R2CCH)[CO2(CO)6]2 (III), and (HCCCHR1R2)Co2(CO)6 (V) were obtained in low yields. Modest yields (5–30%) of methylation products (HCCCR1R2CH3)Co2(Co)6 (II) were produced from I and (C5H5)Fe(CO)2CH3 or (CH3)3Al, accompanied by varying amounts of III. The most efficient route to the methylated derivativesII (25–90% yields) combines the complexed propargyl acetates VIII with (CH3)3Al

Reactions of trifluoroacetonitrile with [Ir(π-2-MeC3H4)(CO)(L)2](L = PPh3 or AsPh3) yield six-memberedchelateringcomplexes [I[graphic omitted]H(CO)(L)](L = PPh3 or AsPh3). A similar reaction of CF3CN with [Ir(π-C3H5)(CO)(PPh3)2] yields [[graphic omitted]H(CO)(PPh3)] together with [[graphic omitted]H(CO)(PPh3)2].
