用钠钾合金处理三苯基硅甲醇，不仅得到了三苯基甲氧基硅烷，还得到了三苯基硅氧基三苯基硅烷和二(三苯基硅氧基)二苯基硅烷。后者的形成被解释为三苯基硅基甲醇的阴离子对其自身的亲核攻击，取代了羟甲基或苯基。三苯基硅基甲酸甲酯是从一种三苯基硅基甲醇中分离得到的。
Treatment of triphenylsilylcarbinol with sodium-potassium alloy gives not only the isomeric ether triphenylmethoxy-silane but also triphenylsiloxytriphenylsilylmethane and bis-(triphenylsilylmethoxy)-diphenylsilane. The formation of these latter products is explained as a nucleophilic attack by the anion of triphenylsilylcarbinol on itself with displacement of either hydroxymethyl or phenyl groups. Triphenylsilylmethyl formate was isolated from a preparation of triphenylsilylcarbinol.
