On May 31, 2005, Kuramshin, A. I.; Asafyeva, E. V.; Cherkasov, R. A. published an article.Formula: C9H21N3O3 The title of the article was Preparation of Complexes η4-4-(1,3-Diphenyl-2-propen-1-one)-η3-3-(1,3,5-triorganyl-1,3,5-triazacyclohexane)carbonyltungsten(0) and Their Reactions with Diethyl Phosphite. And the article contained the following:
New W complexes were prepared of a composition η3-[(1,3,5-triorganyl)-1,3,5-triazacyclohexane]tricarbonyltungsten(0) where a tridentate coordination of the triazinane fragment to the metal center was found. The reaction of tricarbonyl triazinane W complexes with 1,3-diphenyl-2-propen-1-one (chalcone) under thermochem. activation resulted in replacement of two CO mols. in the coordination sphere of W by a chalcone mol. linked to the transition metal atom through a system of π-bonds C:C and C:O. The phosphorylation of η4-(1,3-diphenyl-2-propen-1-one)-η3-[(1,3,5-triphenyl)-1,3,5-triazacyclohexane]monocarbonyltungsten(0) with di-Et phosphite occurred at the carbonyl group of the coordinated heterodiene; the phosphonate thus formed underwent intra-complex phosphonate-phosphate rearrangement affording an organometallic phosphate. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Formula: C9H21N3O3
