The invention provides organosilicon compounds of the formula: ##STR1## in which: N IS 1, 2 OR 3; Each R, which may be identical or different, is a monovalent organic group which contains a carbon-carbon double bond and from 2 to 10 carbon atoms; Each R.sub.1, which may be identical or different, is a straight or branched alkyl radical optionally substituted by one or more halogen atoms or cyano groups; an aryl radical or an alkylaryl radical optionally substituted by one or more halogen atoms; R.sub.2 is a straight or branched divalent alkylene or alkylidene radical possessing up to 4 carbon atoms; X is a divalent radical consisting of, or containing, at least one hetero-atom selected from oxygen, sulphur and nitrogen atoms, the radical being attached to the radical R.sub.2 via a said hetero-atom; G is an organic radical of valency (m+ l) possess from 1 to 30 carbon atoms; m is 1, 2 or 3; And each Y, which may be identical or different, is a functional group selected from: --NO.sub.2, ##STR2## --COOM (where M represents a sodium, potassium or lithium atom); --COOR.sub.4 ; ##STR3## --COCl; --OH; --OR.sub.4 ; ##STR4## --SH; --SR.sub.4 ; ##STR5## --CONH.sub.2 ; --CSNH.sub.2 ; --CN; --CH.sub.2 --NH.sub.2 ; --CHO; ##STR6## --NCO; ##STR7## wherein R.sub.3 represents a hydrogen atom or a straight or branched alkyl radical possessing up to 6 carbon atoms and R.sub.4 represents an alkyl radical possessing up to 4 carbon atoms, with the proviso that two Y groups can together constitute an imide group ##STR8## wherein R.sub.5 represents a hydrogen atom or a straight or branched alkyl radical possessing up to 4 carbon atoms. These are useful intermediates in the preparation of disilanes and silicon polymers, in particular of polyethylenic silicon compounds which can be polymerized with an .alpha., .omega.-dihydrogenopolysiloxane to give thermoplastic elastomers.
