Structures of products of the reactions of halotriorganosilanes with triethyl phosphite and with sodium dialkyl phosphites

1. The reaction of bromotriethylsilane with triethyl phosphite at high temperatures (155-180°) goes with formation mainly of silyl-substituted tervalent phosphorus derivatives, which readily combine with sulfur and undergo Arbuzov reaction with ethyl bromide. 2. In the reactions of trialkylhalosilanes with sodium diethyl phosphite the products are not quinquevalent phosphorus compounds containing the Si-P bond as was supposed earlier, but the isomeric tervalent phosphorus compounds containing the Si-O-P link. 3. The thione-thiol isomerization of Si-P was effected in presence of ethyl bromide.
