1,1-Diboration of 1-Trimethylsilylalkines

Klusik, Hartmut,Pues, Christine,Berndt, Armin

, p. 1042 - 1045 (2007/10/02)

1,2-Di-tert-butyl-1,2-dichlorodiborane(4) (1) and 1,2-dichloro-1,2-bis(dimethylamino)diborane(4) (2) add to 1-trimethylsilylalkines 3a-3d to yield 1,1-bis(tert-butylchloroboryl)alkenes (4) and 1,1-bis(chlorodimethylaminoboryl)alkenes (5), respectively, while reaction of 1 with acetylene, trimethylsilylacetylene, 2-butine and 3-hexine leads to 1,2-bis(tert-butylchloroboryl)alkenes (7).Compounds 4, 5 and 7 are characterized by MS, 1H, 13C and 11B NMR spectroscopy. - Keywords: 1,1- and 1,2-Bis(tert-butylchloroboryl)alkenes
