Arenetricarbonyl-molybdenum and -tungsten complexes

Synthesis, Structure, and Redox Properties of [{(5-C5H5)Co(S2C6H4)}2Mo(CO)2], a Novel Metalladithiolene Cluster

“…[4] However, we could not detect any products in which the benzene ring ligates to Mo, even at different 1/[Mo(CO) 3 (py) 3 ] molar ratios. This is presumably due to the higher reactivity of the electronically unsaturated cobaltadithiolene ring for addition reactions compared to the benzene ring.…”

Synthesis and structures of metallocene complexes of iron(II) and ruthenium(II) derived from 9,9′-spirobifluorene

“…We initially investigated reactions between 4 equivalents of M(CO) 6 (where M = Cr and Mo) and SBF under conditions analogous to those used for the synthesis of M(CO) 3 (g 6 -arene) complexes, including those derived from biphenyl [13][14][15].…”

“…Attempts to prepare tri and tetra addition complexes of SBF from reaction between 3 and 1 and 2 equivalents of [CpRu(CH 3 CN) 3 ][PF 6 ], respectively, in chlorinated Table 1 Selected bond lengths (Å ) and angles (°) for complex 1 C(26)-Ru(1) 2.194(6) C(2)-C(1)-C (14) 117.9(4) C(27)-Ru(1) 2.198(6) C(2)-C(1)-C (25) 109.4(4) C(28)-Ru(1) 2.170(6) C(13)-C(1)-C (25) 111.8(4) C(29)-Ru(1) 2.150(6) C(13)-C(1)-C (14) 115.3(4) C(30)-Ru(1) 2.167(6) C(2)-C(1)-C (13) 101.0(4) C(2)-Ru (1) 2.251 (5) solvents gave no reaction before decomposition of [CpRu(CH 3 CN) 3 ][PF 6 ], which is perhaps unsurprising given the steric congestion evident from the structure of 3a.…”

A study of molybdenum catalysts in the polymerization of 2,5-didodecyl-1,4-dipropynylbenzene

“…Catalysts 3-5 and 7 were prepared as reported [3,4,8]. MoO 2 (acac) 2 /7Al(Et) 3 (6) [3] was prepared by adding a 1.9 M toluene solution of triethylaluminum (Aldrich) to a stirred solution of MoO 2 (acac) 2 (Acros Organics) in freshly distilled toluene.…”
