Methyl 3-benzamido-4,6-di-0-benzoyl-2,3-dideoxy-2-fluoro-a-D-al-tropyranoside (87) was obtained by treatment of methyl 2-benzamido-4,6-0-benzylidene-3-0-p-tolylsulfonyl-a-D-glucopyranoside (84) with tetrabutylammonium fluoride in hexamethylphosphoric triamide, followed by O-debenzylidenation and benzoylation.85 The reaction is... 

Table 16 shows the influence of reaction conditions and of activation reagents such as TMSC1, hexamethylphosphoric triamide (HMPA), M-methyl-imidazole (NMI), saccharin and tetrabutylammonium fluoride (TBAF) on the DS of silyl dextran. For complete silylation, a mixture of 1.8 mol HMDS and 0.2 mol chlorotrimethylsilane (TMSC1) per mol OH groups have to be used. The more reactive TMSC1 reacts in a first step with hydroxyl groups to trimethylsilyl dextran and HC1. Subsequently, the HC1 cleaves HMDS in TMSC1 and NH3 [218]. Complete silylation of dextran could also be carried...

Fujita and Hiyama have developed a homogeneous fluoride ion catalyst system consisting of tetrabutylammonium fluoride (TBAF) or tris(diethylamino)sulfonium difluorotiimethylsilicate (TASF) in hexamethylphosphoric triamide (HMPA), which can promote and complete the hydrosilylation of aldehydes and ketones at room temperature or lower temperatures within one hour in most cases (equation The relative...
