J compounds

A number of significant features appear in this table, in addition to the evidence for -Mn(CO)j compounds. Since no CH3Mn(CO)j was obtained from CpMn(CO)3, the methyl group must clearly come from the ring substituent unless another source of -CH3 is present. Samples of CH3CpMn(CO)3 diluted with 2,2,4-trimethylpentane yielded up to ten...

A second example is the synthesis of the TTF[M(dmit)2]j compounds, where M = Ni, Pd or Pt. Metathesis reaction under inert atmosphere of CH3CN solutions of (TTF)3(BP4)2 and the appropriate metal salt TBA[M(dmit)2] immediately yields insoluble, black, shiny microcrystalline powders. Because TTF[M(dmit)2]j is virtually insoluble in common solvents, its recrystallization from solution is precluded. Therefore, when single crystals are needed some alternative synthesis routes have to be undertaken.

The trimetallic complex [Fe3(CO)8(p-PPh)2(PF3)] has been obtained from the corresponding [Fe3(CO)8(p-PPh)2(MeCN)J compound by displacement of MeCN (method G). The structure, which is based on a square-pyramidal array of three iron and two phosphorus atoms, consists of isomers whose interconversion has been studied by variable-temperature 19F and 31P NMR spectroscopy. A trimetallic PF3 complex containing mercury bonded to two metals results from the reactions...

Physical and chemical data on the MR2L, (R = Me, Et, Ph, allyl, alkenyl, and alkynyl) and MXR(L) (R = Bu, Ph, tolyl X = halide) compounds are greatly lacking, owing to these compounds generally poor thermal stability. The aryl MXR(L) and alkynyl MR2L compounds constitute the most stable classes.The compounds decrease in stability Ba < Sr and XR(L),j compounds form most readily for — I...

Freudenberger and Orchin, in 1982 (48), found that syngas can be incorporated into [Mn(COR)(CO)j] compounds in hexane to give alkoxycar-bonyl species [Eq. (42)]. The reaction terminated at this point the alkoxy-carbonyl was inert toward further reaction with CO and H2. In contrast to the reactions in hexane, the same reactions in sulfolane gave only the aldehydes, RCHO (48). The mechanism shown in Scheme 9 for the formation of the alkoxycarbonyl species was proposed. We believe, however, that the final step shown in the above scheme, namely.
