In an article, published in an article, once mentioned the application of 19845-69-3, Name is 1,6-Bis(diphenylphosphino)hexane,molecular formula is C30H32P2, is a conventional compound. this article was the specific content is as follows.19845-69-3
Cyclopalladated compounds with bridging and chelating diphosphine ligands. Effect of ring size. Crystal and molecular structure of [{Pd[4-(COH)C6H3C(H)=N(Cy)-C2,N] (C1)}2(mu-Ph2PCH2PPh2)]
Treatment of the chloro-bridged dinuclear compound [{Pd[4-(COH)C6H3C(H)=N(Cy)-C2,N]}(mu-Cl)]2 (1) with tertiary diphosphines in 1:1 molar ratio gave [{Pd[4-(COH)C6H3C(H)=N(Cy)-C2,N] (Cl)}2(mu-Ph2PRPPh2)] (R: CH2, 2; CH2CH2, 3; (CH2)4, 4; (CH2)6, 5: Fe(C5H4)2, 6; trans-CH=CH, 7; C?C, 8) with the diphosphine in a bridging mode. When the reaction was carried out in a 1:2 molar ratio in the presence of NH4PF6, the compounds [Pd{4-(COH)C6H3C(H)=NCy-C2,N} (Ph2PRPPh2-P,P)][PF6] (R: CH2, 9; CH2CH2, 10; (CH2)4, 11; (CH2)6, 12; Fe(C5H4)2, 13; 1,2-C6H4, 14; cis-CH=CH, 15; NH, 16) with the diphosphine chelated to the palladium atom, were obtained. 1H, 31P-{1H} and 13C- {1H} NMR, IR and mass spectroscopic data are given. The crystal structure of compound 2 has been determined by X-ray crystallography.
