Synthese und Charakterisierung neuer S‐ und Se‐haltiger Borheterocyclen: 1,2,4,6,3,5‐Thiatriazadiborinane, 1,4,2,6,3,5‐Thiaselenadiazadiborinane und 1,2,3‐Diselenaborole

Abstract: 3,5-Dimethyl-l,2,4,3,5-dithiazadiborolidine 1 reagieren mit Schwefeldiimiden unter Ersatz der Disulfanbrucke zu 1,2,4,6,3,5-Thiatriazadiborinanen (2ac). Ein bemerkenswert stabiles Derivat dieses Heterocyclus, substituiert rnit zwei N-tert-Butylschwefeldiimid-Resten (4), erhalt man durch Umsetzung von 3J-Dibrom-4-phenyl-1,2,4,3,5-dithiazadiborolidin (3) mit N-tert-Butyl-N'-(trimethylsi1yl)schwefeldiimid. 1,2,4,3,5-TriseIenadiborolan 5a ergibt mit Schwefeldiimiden 1,4,2,6,3,5-Thiaselenadiazadiborinane (6 ac). 1,… Show more

“…Although some applications of noncyclic selenoboranes1,2 have been described,3 their cyclic analogues appear to be even more intriguing due to their potential use in heterocyclic synthesis4,5 or as ligands for transition‐metal complexes 6. Theformer has been shown by the conversion of 1,3,4,2,5‐triselenaborolanes into novel ring systems through reactions with isocyanates5a or alkynes 5b,5c. Recently, we prepared the first stable 1,3,2‐diselenaborolane derivatives 2 (Scheme )7 starting from the silane 1 8 through exchange reactions.…”
