The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Tris(triphenylphosphine)chlororhodium( cas:14694-95-2 ) is researched.Quality Control of Tris(triphenylphosphine)chlororhodium.Fernandes, Manuel A.; Mashabane, Gcinaphi Z.; Weber, Rosemarie; Carlton, Laurence published the article 《Structural study of analogues of Wilkinson’s compound [Rh(X)(PPh3)3] (X = NCO, NCS, N3, N(CN)2) and derivatives [Rh(NCO)(O2)(PPh3)3] and [Rh(η6-C6H5B(NCO)Ph2)(PPh3)2]》 about this compound( cas:14694-95-2 ) in Polyhedron. Keywords: Wilkinson rhodium triphenylphosphine isocyanate isothiocyanate azide cyanamide preparation structure; crystal mol structure rhodium triphenylphosphine isocyanate isothiocyanate azide cyanamide; isocyanatoboryl benzene rhodium triphenylphosphine preparation crystal mol structure. Let’s learn more about this compound (cas:14694-95-2).
Structures are reported for the complexes [Rh(X)(PPh3)3] (X = NCO, NCS, N3, N(CN)2) and for the products obtained by the reaction of the NCO complex with O2 (giving [Rh(NCO)(O2)(PPh3)3]) and with triphenylboron (giving [Rh(η6-C6H5B(NCO)Ph2)(PPh3)2]), a reaction involving an unusual ligand migration from rhodium to boron. The N-bonded attachment of the cyanate and thiocyanate ligands in [Rh(X)(PPh3)3] (X = NCO, NCS) is confirmed by 31P{15N} NMR.
The article 《Structural study of analogues of Wilkinson’s compound [Rh(X)(PPh3)3] (X = NCO, NCS, N3, N(CN)2) and derivatives [Rh(NCO)(O2)(PPh3)3] and [Rh(η6-C6H5B(NCO)Ph2)(PPh3)2]》 also mentions many details about this compound(14694-95-2)Quality Control of Tris(triphenylphosphine)chlororhodium, you can pay attention to it, because details determine success or failure
