A trans-silylation route to 1,3-dichloro-1,3-dihydridodisilazanes, a novel class of polyfunctional disilazane, is described.Thus, heating hexamethyl- or heptamethyl-disilazane under reflux in the presence of an excess of dichlorohydrogenosilane R¹SiHCl2, led to compounds of formula (R¹ClHSi)2NR² (R¹=Me, Et, Vi or Ph and R²=H; R¹=Me and R²=Me) in high yield.The exchange of chlorinated organosilicon moieties was strongly facilited by a catalytic amount of (n-Bu4N)F.Interpretation of the results and a few chemical properties of these novel disilazanes arereported.Key words: Silicon; Silazanes; Synthesis; Dichlorodisilazanes; Dihydridodisilazanes
