heterocyclic manifolds. Reduction of a dimeric [RGeCl]2 species (R = anionic NHO, [(MeCNDipp)2C═CH]-; Dipp = 2,6-iPr2C6H3) did not give the expected acyclic RGeGeR analogue of an alkyne, but rather ligand migration/disproportionation transpired to yield the known diorganogermylene R2Ge and Ge metal. This process was examined computationally, and the ability of the reported anionic NHO to undergo atom migration

calculated in order to comprehend the electronic properties for these two rotamers for each HAPAs. Besides, the stericeffect of HAPAs was estimated in terms of the Percent Buried Volume (%Vbur). This model has shown that 7a has similar steric property to that of PCy3, which is an effective ligand in Suzuki-coupling reactions.

catalytic benzene alkenylation using different diimine ligated Rh(I) acetatecomplexes and Cu(OAc)2 as the oxidant revealed statistically identical results in terms of activity and product selectivity. Under ethylene pressure, two representative diimine ligated rhodium(I) acetatecomplexes were demonstrated to exchange the diimine ligand with ethylene rapidly to form [Rh(μ-OAc)(η2-C2H4)2]2 and free diimine
使用不同的二亚胺连接的乙酸Rh(I)络合物和Cu(OAc)2作为氧化剂的催化苯烯基化反应的研究表明,就活性和产物选择性而言,统计学上相同的结果。下的乙烯压力,两个代表性二亚胺连接铑(I)配合物乙酸被证明与乙烯迅速交换二亚胺配体与形式的[Rh(μ-OAC)(η 2 -C 2 H ^ 4)2 ] 2和自由二亚胺。因此,得出的结论是,在催化条件下,二亚胺配体不太可能与活性Rh催化剂配位。在使用市售的铜(OAC)催化条件下150℃ 2作为氧化剂时,铑[Rh(μ-OAC)(η 2-C 2 H 4)2 ] 2经历快速分解以形成催化惰性和不溶性Rh物质,然后逐渐溶解不溶性Rh形成可溶Rh,对苯乙烯生产具有活性。因此,在某些条件下观察到的诱导期很可能是由于形成不溶的Rh(快速),然后再溶解Rh(缓慢)所致。通过使用已预热的可溶性Cu(II)氧化剂或Cu(OAc)2,可以抑制Rh的分解过程并保持催化活性Rh

reactivities. Catalytic 1,4-hydrosilylation of 1,3-enynes may present the straightforward strategy for synthesis of silylallenes. However, the transition-metal-catalyzed reaction has not been successful due to poor selectivity and very limited substrate scopes. We report here the efficient and selective 1,4-hydrosilylation of branched 1,3-enynes enabled by the ene-diamido rare-earth ate catalysts using both alkyl

Cp#2Yb(THF)2 with the corresponding DADs in a 1:1 molar ratio. These reactions are accompanied by oxidation of the Yb(II) to Yb(III), cleavage of one Cp#–Yb bond, oxidation of cyclopentadienyl anion, and reduction of the diazabutadiene to dianionic form. It was found that the substituents by the DAD nitrogens (2,6-iPr2C6H3 vs 2,6-Me2C6H3) and imino carbons (H vs Me) do not affect the reaction outcome
