The synthesis of 1,1,3,3-tetrasubstituted 1,3-disilicacyclobutanes

Summary1.We have proposed a one step method for preparing 1,3-disilicacyclobutanes from chloromethyl chlorosilanes and magnesium in ether.2.This method is general and permits preparation of previously unknown 1,3-disilicacyclobutanes with functional groups on the silicon atom.

Some features of the sintering of niobium carbide

SummaryA study was made of the sintering of niobium carbide in electric furnaces. It is shown that niobium carbide parts can be sintered at relatively low temperatures (2400–2500°C) if activating additions are used.
