The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Tris(triphenylphosphine)chlororhodium, is researched, Molecular C54H45ClP3Rh, CAS is 14694-95-2, about Platinum complexes containing or derived from olefinic phosphines P(X)((CH2)6CH=CH2)2 (X = OH, Ph, (CH2)6CH=CH2); ring closing metathesis, structures, and trans/cis isomerizations, the main research direction is phosphine bicyclic macrocyclic diphosphine platinum complex preparation crystal structure; ring closing metathesis bicyclic macrocyclic diphosphine platinum compound preparation.Recommanded Product: 14694-95-2.

The reaction of (O=)PH((CH2)6CH=CH2)2 (2.0 equiv) and PtCl2 in toluene gives trans-PtCl2(P(OH)((CH2)6CH=CH2)2)2 in 68% yield as a 82:18 mixture of Pt-Cl···H-OP hydrogen bond isomers. Addition of Grubbs’ first generation catalyst followed by hydrogenation (5 bar, cat. RhCl(PPh3)3 or PtO2) affords the doubly trans spanning macrocyclic diphosphine adduct trans- (31-9% crude yields). A crystal structure shows that the two OH groups are anti, and hydrogen bond to opposite Cl-Pt-Cl chlorine atoms. The reaction of P(Ph)((CH2)6CH=CH2)2 (2.0 equiv) and PtCl2 in toluene gives cis-PtCl2(P(Ph)((CH2)6CH=CH2)2)2 (cis-5, 40%) and trans-5 (8%). The crystal structure of the former is determined The trans/cis equilibrium ratios of these and related complexes are probed by DFT. Attempts to crystallize trans- (trans-7′), which is a minor product from a published metathesis/hydrogenation sequence involving trans-PtCl2(P((CH2)6CH=CH2)3)2, give only cis-7′, as established by 31P NMR and crystallog.
