Abstract

A method using (2-cyanoethyl) dhethyl (dlethyiamino) siiane to form derivatlves with phenoxy acid herbkldes and related compounds Is presented. Results obtained with 18 compounds demonstrate that the reactlon is quantitative and complete within minutes at room temperature. The derlvatives formed can readlly be analyzed by gas chromatography using a selective nitrogen-phosphorus detector which ellmlnates the need for rigourous ...
