| Abstract | Upon aminoboration of carbonyl sulfide 1,2-addition to the carbonyl group is observed. In tris(dimethylamino)borane insertion into two of the B−N bonds occurs, while in bis(dimethylamino)chloroborane only one B−N bond reacts with OCS. In tris(2,2-dimethylhydrazino)borane all three B−N bonds react with CO2, while with CS2 no insertion reaction is observed under comparable conditions. Tris(dimethylamino)borane reacts with phosgene and thiophosgene with formation of bis(dimethylamino)chloroborane and substituted carbamides.ZusammenfassungBei der Aminoborierung von Carbonylsulfid erfolgt 1,2-Addition an die Carbonylgruppe, wobei in Tris(dimethylamino)boran zwei der B−N-Bindungen, in Bis(dimethylamino)chlorboran nur eine B−N-Bindung reagieren. In Tris(2,2-dimethylhydrazino)boran reagieren alle drei B−N-Bindungen mit CO2; mit CS2 erfolgt unter den gleichen Bedingungen keine Reaktion. Mit Phosgen und Thiophosgen reagiert Tris(dimethylamino)boran unter Bildung von Bis(dimethylamino)chlorboran und substituierter Carbamide. |
