In an article, published in an article, once mentioned the application of 13991-08-7, Name is 1,2-Bis(diphenylphosphino)benzene,molecular formula is C30H24P2, is a conventional compound. this article was the specific content is as follows.Computed Properties of C30H24P2
The reactivity of the sigma,pi-thienyl complex [Fe2(CO)6(mu-Th)(mu-PTh2)] (1) towards a range of phosphines has been studied. With PR3 (R = Ph, Th) carbonyl substitution affords [Fe2(CO)5(PR3)(mu-Th)(mu-PTh2)] (2a-b) as the major product, with smaller amounts of the thienyl-acyl complexes [Fe2(CO)5(PR3)(mu-OC-Th)(mu-PTh2)] (3a-b) resulting from a migratory carbonyl insertion into the thienyl ligand. With diphosphines, thienyl-acyl complexes are the major products in all cases. With dppm, [Fe2(CO)4(mu-dppm)(mu-OC-Th)(mu-PTh2)] (4) results in which the diphosphine bridges the iron-iron bond, while with other diphosphines the chelate complexes [Fe2(CO)4(kappa2-diphosphine)(mu-OC-Th)(mu-PTh2)] (5-9) are isolated, as established through crystallographic studies on [Fe2(CO)4(kappa2-dppe)(mu-OC-Th)(mu-PTh2)] (5) and [Fe2(CO)4(kappa2-dppb)(mu-OC-Th)(mu-PTh2)] (9), both of which show that the diphosphine binds selectively to the oxygen-bound metal centre with phosphorus atoms lying trans to the metal-metal bond and mu-PTh2 bridge. With 1,2-bis(diphenylphosphino)benzene (dppb), [Fe2(CO)5{mu,kappa2-C6H4PPh(C6H4)PPh2}(mu-PTh2)] (10) is isolated in low yields and results from cyclometalation of a phenyl ring and putative elimination of thiophene. In a separate experiment, it has been shown that heating 9 results in the slow formation of 10.
