有机硅烷类化合物主要应用在有机合成及有机硅材料领域。在有机合成中，硅烷作为羟基 保护基大量存在，如三甲基氯硅烷，TBSCI,有时作为一个合成子载体存在，如乙烯基三甲基 硅烷，烯丙基三甲基硅烷，六甲基二硅硫烷等，从而实现相应的官能团化反应。有机硅材料领域有硅烷偶联剂、硅油（硅脂、硅乳液、硅表面活性剂）、高温硫化硅橡胶、液体硅橡胶、硅 树脂、封端剂，含硅复合共聚物等。

        • {ALF} CsF promotes the reduction of aldehydes and ketones to alcohols: J. Organomet. Chem., 148, C1 (1978); 172, 143 (1979). Esters can be reduced at elevated temperatures: Synthesis, 558 (1981). Aldehydes and ketones are also reduced in the presence of TBAF: J. Org. Chem., 53, 5415 (1988).
        • {ALF} In combination with an equivalent of Titanium(IV)­ isopropoxide, A13703, a mild, one-pot reduction of tertiary amides to aldehydes can be accomplished in high yield. The initial product is the enamine which can be readily hydrolyzed in situ to the aldehyde: Angew. Chem. Int. Ed., 35, 1515 (1996):
        • {ALF} In the presence of Tetrakis(triphenyl­phosphine)­palladium(0)­, 10548, effects the reductive cleavage of allylic acetates: J. Org. Chem., 48, 3545 (1983). With the same catalyst and a Lewis acid such as zinc chloride, ɑß-unsaturated aldehydes, ketones and esters are reduced to their saturated counterparts: J. Am. Chem. Soc., 108, 7314 (1986).
        • {ALF} Protection of diols as diphenylsilylenes can be effected in the presence of CsF: J. Organomet. Chem., 282, 155 (1985). See Diphenyl­dichlorosilane, A12051, and Appendix 4.
        • {ALF} Reducing agent used in combination with F- or other catalyst.
