The mass spectrometric behavior of new tris(polyoxalkyl)amines (tridents) 1-5 have been studied and compared with N-(3,6,9,12-tetraoxatridecyl)-16-aza-18-crown-6 (6) and 1-morpholino-3,6,9-trioxadecane (7).The peculiar fragmentation patterns are emphasized.

Silane, SiH4, and diochlorosilane, particularly suitable for the preparation of silicon are readily obtained by disproportionating trichlorosilane to dichlorosilane and, ultimately silane by reacting: (a) a silane containing at least one Si-H bond, of the general formula Rn Hm SiX4-(n+m) wherein R represents an alkyl or aryl group, x represents a halogen or an alkoxy group, n is an integer equal to 0, 1, 2 or 3 and m is an integer equal to 1, 2 or 3, and (b) a catalyst system comprising an ionic inorganic salt of the formula M+ A- and a compound capable of at least partially dissociating the salt by complexing its cation M+.
