Carbon-13 NMR has been used to show that the deoxygenation of isocyanates to isonitriles with t-butyldiphenylsilyl lithium proceeds via the intermediates (7 and 8). The silyl carboxamide (1) can be isolated but is thermally unstable rearranging to a mixture of silyl formamides (2). The spectroscopic properties of the silyl carboxamide (1) were found to be substantially different from those previously
已经使用碳13 NMR来证明异氰酸酯与叔丁基二苯基甲硅烷基锂的脱氧反应是通过中间体(7和8)进行的。可以分离甲硅烷基羧酰胺(1),但是热不稳定,重排成甲硅烷基甲酰胺(2)的混合物。发现甲硅烷基羧酰胺(1)的光谱性质与先前针对此类化合物所要求的那些实质上不同。
