室温下SmI~2/ THF/ HMPA 体系可顺利地将异腈酸酯(RNCO)还原偶联成草酰胺衍生物(RNHCOCONHR),同样条件下, RNCO可以和PhCOCl, R^1X等发生交叉偶联得到酰胺; 而异硫腈酸酯在类似条件下却发生脱硫反应,得到异腈。

The SmI~2/ THF/ HMPA system can promote the reductive coupling reaction of RNCO successfully to give the oxalic diamides at room temperature in good yields. The same system can also promote the cross-coupling reaction of RNCO with PhCOCl and RX to give amides. But the RNCS was desulfurized to give isocyanides in high yields under the similar conditions.

Key words: ISOTHIOCYANATE, COUPLING REACTION
