Abstract
Bis(silyl)alkanes represented by the formulas (III), (IV) and (V) ##STR1## wherein R is H or phenyl, R' is a hydrogen atom or C.sub.1-4 alkyl and n is an integer ranging from 1 to 4. The present invention also provides a method for preparation of the bis(silyl)alkanes comprising the steps of mixing an organic compound, which is represented by the formula (I) and has a chloro at each side of its molecule, with a hydrogen chloride or an organic chloride represented by the formula (II), the organic chloride being capable of generating the hydrogen chloride during its reaction, in order to provide a mixture and directly reacting this mixture with a metal silicon at a reaction temperature of 260.degree. C.-370.degree. C. in the presence of a copper catalyst.
