Synthetic Route of 92361-49-4. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 92361-49-4, Name is Chloro(pentamethylcyclopentadienyl)bis(triphenylphosphine)ruthenium(II). In a document type is Article, introducing its new discovery.
Reactions between HC?CC?CSiMe3 and several ruthenium halide precursors have given the complexes Ru(C?CC?CSiMe 3)(L2) Cp? [Cp? = Cp, L = CO (1), PPh 3 (2); Cp? = Cp*, L2 = dppe (3)]. Proto-desilylation of 2 and 3 have given unsubstituted buta-1,3-diyn-1-y1 complexes Ru(C?CC?CH)(L2) Cp? [Cp? = Cp, L = PPh3 (5); Cp? = Cp*, L2 = dppe (6)]. Replacement of H in 5 or 6 with Au(PR3) groups was achieved in reactions with AuCl(PR3) in the presence of KN(SiMe3) 2 to give Ru(C?CC?CAu(PR3)}(L 2)Cp? [Cp? = Cp, L = PPh3, R = Ph (7); Cp? = Cp*, L2 = dppe, R = Ph (8), tol (9)]. The asymmetrically end-capped {Cp(Ph3P)2Ru} C?CC?C{Ru(dppe)Cp*} (10) was obtained from Ru(C?CC?CH)(dppe)Cp? and RuCl(PPh3)2Cp. Single-crystal X-ray structural determinations of 1-3 and 6-9 are reported, with a comparative determination of the structure of Fe(C?CC?CSiMe 3)(dppe)Cp? (4), and those of a fifth polymorph of {Ru(PPh 3)2Cp}2(muC?CC?C) (12), and {Ru(dppe)Cp}2(mu-C?CC?C) (13).
