摘要

As an alternative to boronic acids , 6 organosilicon compounds have attracted much attention in recent years due to their low toxicity and high stability to both air and moisture. Especially aryltriethoxysilanes are low-cost and can be readily prepared nowadays in one step by a Barbier-type reaction of the corresponding aryl bromide and tetraethoxysilane at room temperature. 7 In contrast to arylboronic acids, 8 arylsiloxanes are easily purified by distillation or chromatography . ...
