A simple method for the synthesis of new bio-based silane coupling agents (SCAs) with a terpene aromatic core by the functionalization of cheap, natural eugenol and its sulfur derivatives using the hydrosilylation of the C=C bonds with HSi(OEt)3, followed by nucleophilic substitution reactions of OH/SH groups is presented. The obtained alkoxysilanes possess different polymer-reactive functionalities
通过使用 HSi(OEt) 3对 C=C 键进行氢化硅烷化,对廉价的天然丁子香酚及其硫衍生物进行功能化,合成具有萜烯芳香核的新型生物基硅烷偶联剂 (SCAs) 的简单方法,随后是 OH/SH 基团的亲核取代反应。获得的烷氧基硅烷具有不同的聚合物反应性官能团(烯基、环氧化物、硫杂丙环、硫代氨基甲酰基、硫酯、硫醚部分)。这组新的生物 SCA 使用1 H、13 C、29 Si NMR、FT-IR、GC-MS 和 HRMS 或元素分析进行了全面表征。还讨论了它们作为轮胎橡胶添加剂的应用实例及其对几个因素的影响。
