Distibines reactions

In order to circumvent any Si contamination in the resulting material hlms, there was clearly a need for non-silyl substituted precursors. Consequently, we focused on the use of completely alkyl-substituted heterocycles, which are now easily accessible in high yields by the distibine reaction pathway.

An alternative preparative route to R2QER acid esters (Q = P, As, Sb, Bi E = S, Se, Te) of interest due to its generally applicability to all the heavier group 15 and 16 elements, is the dismutation reaction between diorganodichalco-genides and tetraorgano-diphosphines, -diarsines, -distibines or -dibismuthines (Equation 17).2... 

Bidentate coordination leading to bis-adducts is observed in reactions of distibines with aluminium or gallium trialkyls in absence of solvent at low temperatures (Equation 2).76... 

A general reaction of binuclear distibine complexes is the fission of the Sb-Sb bond and transformation of the R2Sb-SbR2 into a R2Sb groups. 

In sharp contrast to the intensely studied reactions of dipenteles with transition metal compounds, reactions with group 13 metal compounds are almost unknown. Only two diphosphine-borane bisadducts of Type C ([H3B]2[Me4P2], [H2(Br)B]2[Me4P2]) have been synthesized and structurally characterized65 but no diarsine, distibine or dibismuthine adducts. We, therefore, became interested in the synthesis of such compounds, focusing...

Reaction of (C6H5)2SbNa with (CH2)2C12 gave the distibine [(C6H5)2Sb]2 (1,8). 

Oxygen in the enviromnent of three antimony atoms exists also in the planar oxonium salt [(Mc2Sb)30]Br, which is formed by reaction of (Mc2Sb)20 with Me2SbBr. Tetraaryldistibine oxides are formed by air oxidation of the corresponding distibines. ...
