Application of 1038-95-5, An article , which mentions 1038-95-5, molecular formula is C21H21P. The compound – Tri-p-tolylphosphine played an important role in people’s production and life.
The reactions of 3,5-diethynylpyridine (Py(C=CH)2) with PPN[Au(acac) 2] (2.5:1; PPN = Ph3P=N=PPh3) or with [AuCl(SMe2)] and NEt3 (1:2:2) give respectively PPN[Au{C=C(Py)-C=CH}2] (1) and [Au2{mu-(C=C) 2Py}]n (2). Complex 2 reacts with monodentate ligands (1:2) or with 1,6-bis(diphenylphosphino)hexane (dpph, 1:1) to give neutral dinuclear complexes of the general formula [(AuL)2{mu-(C=C) 2Py}] (L = CN’Bu (3), PMe3 (4), PPh3 (5), PTo3 (To = CeH4Me-4) (6); Au2L 2 = Au2(mu-dpph) (7)). The reactions of 6 with the complexes [MCI] and TITfO (1:1:1) (TfO = CF3SO3) give the cationic trinuclear complexes [M{Py(C=CAuPTo3)2}]TfO (M = AuPTo3 (8), cis-PtCl(PPh3)2 (9)). The crystal structure of complex 6 has been determined.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1038-95-5, help many people in the next few years., Electric Literature of 1038-95-5
