我们提出了一条合成含有苯并-15-冠-5取代基的某些有机硅冠醚化合物的简易路线。通过Wittig反应合成的4’-乙烯基苯并-15-冠-5,经过双键上的硅氢加成反应,得到几种新型含有冠醚基团的有机硅烷或氯硅烷。后者可以进一步烷氧基化或者水解成冠醚取代的聚有机硅氧烷。此外,还测定了它们对碱金属离子的络合容量和作为相转移催化剂的能力。
We present an easy route to synthesize some of the silicone crown ether compounds containing benzo-15-crown-5 substituents. The 4’-vinylbenzo-15-crown-5 synthesized by the Wittig reaction was subjected to hydrosilylation reaction on double bonds to obtain several novel crown ether-containing organosilanes or chlorosilanes. The latter can be further alkoxylated or hydrolyzed to crown ether-substituted polyorganosiloxanes. In addition, their complexing capacity for alkali metal ions and their ability as phase transfer catalysts were also determined.
