the quick preparation of SnBu2RX (Bu = n-Bu) has been developed using microwave irradiation and column chromatography in acidic alumina. The method can be a good alternative particularly for easy and quick preparation of small amounts for test purposes and, in general, for the synthesis of compounds that cannot be purified by fractional distillation due to thermal lability or low volatility.
已经开发了一种使用微波辐射和酸性氧化铝柱色谱法快速制备SnBu 2 RX(Bu = n -Bu)的简便方法。该方法可以是一种很好的选择,特别是对于出于测试目的的简便快速制备,以及通常用于合成由于热不稳定性或低挥发性而无法通过分馏纯化的化合物的合成而言。

The Stillecoupling can be carried out in a batch process using insoluble tin supports. The new type of support consists of stannylated polymers based on the vinylic polynorbornene skeleton that allow one to use a set-up where the tin reagent is immobilized in a column. The immobilized stannylated polymeric reagent can be easily reused. The coupling products are thus obtained by a very simple work-up
