New mono- or polyhydroxylated (carbo)silane cpds.

摘要

Mono- or polyhydroxylated silanes and carbosilane cpds. of formula (I) are new (A1)Si(R)2(R1)Si(R)(A)(R1)xSi(R)2(R1)yE(R)2(A2) (I) (where R = 1-22 C alkyl or aryl; R1 = 1-22 C alkylene; A = B(C)(D); B = 3-12 C alk(en)ylene which is opt. substd. by O, S or N; C = a straight chain and/or cyclic hydrocarbon resistor contg. 3-18 C; D = H, alkyl, alkenyl or aryl contg. 2-22 C and opt. substd. by O, N or S atoms, or a straight chain and/or cyclic polyhydroxylated hydrocarbon residue contg. 3-18 C (opt. substd. by 2-22 C alk(en)ylene unit contg. N, O, or S atoms); x, y = 0-1000; A1 = R or A (when x is more than O), or A (when x is O); E = Si (when x is more than O), or Si or carbon when x and y are O; A2 = R (when E is carbon), or R or A (when E is Si); E = 3-12 C alk(en)ylene unit which is substd. by N, O or S).
