TITLEs Formation reactions of triethyl-siloxy-borosiloxanes

TEXTt For the purpose of synthesizing triethyl-ailory4diethory-borotit
the authors of the present paper studied the reaction of triefhyl-hydroxy-
-silane with boric acid ethyl eater. Experiments disclosed that triz.-
-triethyl-siloxy-boron is formed even by reacting borio acid 0-hyl eztjr
with triethyl-hydro3ty-silane in a molar ratio; triethyl-siloxy-diethory-
-boron could not be separated* The latter is probably subjected to di,_
proportionation during distillationt forming a stable compoun4, namely
trio-triethyl-siloxy-boron. In subsequent experimentag borio eater wap
first condensed with triethyl-hydroxy-silonev combined with a diet-illation
of the alcohol separated during the reactions
