General Synthesis of Trialkyl-And Dialkylarylsilylboranes: Versatile Silicon Nucleophiles in Organic Synthesis

Compared to carbon-based nucleophiles, the number of silicon-based nucleophiles that is currently available remains limited, which significantly hampers the structural diversity of synthetically accessible silicon-based molecules. Given the high synthetic

Contributions to the chemistry of silicon-sulphur compounds LV. Isosteric isobutyl(isopropoxy)silanethiols. Preparation and spectroscopic properties

The reactions of isobutyl(isopropoxy)silyl bromides i-Bun(i-PrO)3-nSiBr (n=0-3) with H2S in the presence of Et3N yield the corresponding silanethiols, i-Bun(i-PrO)3-nSiSH.The transition energy ?-s* and the IP of Si-S bond, as wel as the first IP of sulphur lone pairs do not change significantly as the number of electronegative i-PrO groups is varied.The geminal anomeric effect seems to be the reason for the increased reactivity of i-Bu(i-PrO)2SiSH and i-Bu(i-PrO)2SiH.
