偶氮羰基官能化的硅烷
摘要：
本发明提供了通式I的偶氮羰基官能化的硅烷(R1)3-a(R2)aSi-RI-NH-C(O)-N＝N-R4。其由如下制备方法制得：在第一步中，式H2N-NH-R4的肼与通式(R1)3-a(R2)aSi-RI-NCO的异氰酸硅烷反应，并且在第二步中，用氧化剂氧化第一步的产物；或者在第一步中，式H2N-NH-R4的肼与通式Cl-C(O)-O-R5的酰卤反应，在第二步中，用氧化剂氧化第一步的产物，并且在第三步中，第二步的产物与通式(R1)3-a(R2)aSi-RI-NH2的氨基硅烷反应。所述偶氮羰基官能化的硅烷可以用于模制品。
摘要（英）：

The invention provides azocarbonyl-functionalized silanes of the general formula I (R1) 3-a (R2) a Si-R I -NH-C(O)-N=N-R 4 . They are prepared by a procedure in which in a first step hydrazine of the formula H 2 N-NH-R 4 reacts with an isocyanatosilane of the general formula (R1) 3-a (R2) a Si-R I -NCO, and in a second step the product of the first step is oxidized with an oxidant, or in which in a first step hydrazine of the formula H 2 N-NH-R 4 reacts with an acyl halide of the general formula Cl-C(O)-O-R 5 , in a second step the product of the first step is oxidized with an oxidant and in a third step the product of the second step reacts with an aminosilane of the general formula (R 1 ) 3-a (R 2 ) a Si-R I -NH 2 . The azocarbonyl-functionalized silanes may be used for moldings.
