Synthese, Molekül-und Kristallstruktur von 3,5-Dimethyl-2,6-bistrimethylsilyl- 1-thia-2,4,6-triaza-3,5-diborinan-wolframpentacarbonyl/ Synthesis, Molecular and Crystal Structure of 3,5-Dimethyl-2,6-bistrimethylsilyl- 1-thia-2,4,6-triaza-3,5-diborinane-tungstenpentacarbonyl

Abstract

Abstract The am monolysis of 3,5-dim ethyl-2,6-bistrimethylsilyl-1,4-dithia-2,6-diaza-3,5-diborinane leads to 3,5-dim ethyl-2,6-bistrim ethylsilyl-1-thia-2,4,6-triaza-3,5-diborinane, which reacts with tungstenpentacarbonyl · TH F to give the title-com pound. 1H , 11B , 13C, 14N , 29Si NMR spectra, IR and MS data, and the results of an X-ray analysis are reported.
