Oxidative group transfer to Co(I) affords a terminal Co(III) imido complex.
The synthesis of the first terminal imido complex of cobalt, [PhBP3]CoN-p-tolyl, is reported. Its synthesis proceeds by oxidative group transfer from cobalt(I) upon addition of tolyl azide at room temperature. This species and a related eta1-diazoalkane adduct have been structurally characterized. The diamagnetic imido complex [PhBP3]CoN-p-tolyl reacts with CO to liberate isocyanate and the cob...
متن کاملIsocyanate and carbodiimide synthesis by nitrene-group-transfer from a nickel(II) imido complex.
The imido complex (dtbpe)Ni(N(2,6-(CHMe2)2C6H3)) reacts with CO and CNCH2Ph with addition at the Ni-N bond to give (dtbpe)Ni(C,N:eta 2-C(O)N(2,6-(CHMe2)2C6H3)) and (dtbpe)Ni(C,N:eta 2-C(NCH2Ph)N(2,6-(CHMe2)2C6H3)); both complexes react further with CO to liberate the isocyanate and carbodiimide ligands with formation of (dtbpe)Ni(CO)2.
متن کاملA scandium terminal imido complex: synthesis, structure and DFT studies.
The first rare earth metal terminal imido complex has been isolated and structurally characterized. The complex has an extremely short M-N bond length and a nearly linear M-N-C angle. DFT studies showed two p orbitals of N(imido) atom form two bonds with two d orbitals of rare earth metal ion.
متن کاملChemoselective silyl transfer in the Mukaiyama aldol reaction promoted by super silyl Lewis acid.
In the silyl Lewis acid-promoted Mukaiyama aldol reaction, the steric and electronic properties of the silyl group on the silyl Lewis acid influence the reaction mechanism and product distribution. When super silyl triflates such as (TMS)3SiOTf and (TES)3SiOTf are used as Lewis acids, the silyl group of the silyl enol ether chemoselectively transfers to the product. The mechanistic details have...
