 Title    Koordinationschemie ambivalenter Liganden, VIII 1 Synthese und Reaktivität ionischer und kovalenter Sulfinato-Komplexe von Tetraorganyl-VB-Elementen des Typs R4'E02SR Synthesis and Reactivity of Ionic and Covalent Sulfinato Complexes of Tetraorganyl-VB-Elements of the Type R4'E02SR  
 Abstract    The synthesis of the sulfinato derivatives 1-7 of pentavalent YB-elements follows equation (2). These compounds differ significantly in their physical and chemical properties and in their structures. In between the extremes of the purely ionic tetramethylam-monium sulfinates la-c and the typically covalent and pentacoordinated tetraorganyl-sulfinato-O-stiboranes 6-7, there are the hexa-or pentavalent compounds of phosphorus and arsenic 2 and 4 or 3 and 5 with sulfinato-0,0' or sulftnato-0 linkage, which dissociate readily into their ionic components. 1 a-c are suitable for the synthesis of sulfones according to equation (3). All of the methylsulfinato derivatives can be easily transformed (equation (4)) into the corresponding sulfonates by air oxidation. Only the tetraphenylsulfinato-O-stiboranes 7 a-c show S02-elimination forming pentaorganylstiboranes (equation (5)). IR, mass and in some cases NMR spectra are reported.
