Silanes hydrogen-deuterium exchange

The surface of silica is highly reactive and hydroxyl groups exchange hydrogen for deuterium with D20 [14—16] but not with D2. They can be replaced by Cl from Cl2 or CC14 [16] and they react with silanes and aluminium chloride [15,19], Surface alcoholates are formed when silica is contacted with primary or secondary alcohols [20] either by the reaction with hydroxyl groups... 

NiCl2 (229) (eq. [63]). Deuterium-hydrogen exchange was shown to occur with retention of configuration at the silicon atom of the optically active deuterio-silane 154 (229) (eq. [64]).
