On October 1, 2017, Bulygina, Ludmila A.; Kagramanov, Nikolay D.; Khrushcheva, Natalya S.; Lyssenko, Konstantin A.; Peregudov, Aleksander S.; Sokolov, Viacheslav I. published an article.Application of 227940-70-7 The title of the article was Unsymmetrical pincer CNN palladium complex of 7-ferrocenylmethyl-3-methyl-3,7-diazabicyclo[3.3.1]nonane. And the article contained the following:
The new unsym. ferrocenyl containing bispidine derivative 7 was synthesized as a ligand precursor in five steps starting from N-Boc-4-oxopiperidine. The corresponding palladium CNN pincer complex 8 was prepared by direct cyclopalladation of the ligand 7 with Li2PdCl4 in MeOH. The mol. structure of the obtained palladacycle was determined by multinuclear NMR (1H, 13C, 15N) and confirmed by x-ray diffraction anal. The pincer complex 8 demonstrated high catalytic activity in some cross-coupling reactions of aryl halides with phenylboronic acid, norbornene and Et acrylate. The experimental process involved the reaction of tert-Butyl 7-benzyl-9-oxo-3,7-diazabicyclo[3.3.1]nonane-3-carboxylate(cas: 227940-70-7).Application of 227940-70-7
