摘要： Trimethylsilyl cyanide, (CH.sub.3).sub.3 Si-CN, is obtained by reacting trimethylsilyl chloride with an approximately equimolar amount of an alkali metal cyanide in the absence of water and in the presence of catalytic, sub-stoichiometric amounts of both an alkali metal iodide and N-methylpyrrolidone, at a temperature of from 15.degree.-25.degree. C.

摘要： Tertiary alkyl cyanides of the general formula ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 represent identical or different alkyl group or, together with the tertiary carbon atom to which they are bonded, form a polycycloalkyl group, orR.sup.1 and R.sup.2, together with the tertiary carbon atom to which they are bonded, form a cycloalkyl group or a bicycloalkyl group, the alkyl groups, polycycloalkyl group, cycloalkyl group or bicycloalkyl group being optionally substituted by suitable substituents (as hereinbefore defined),are obtained in good yields by a process in which a tertiary alkyl halide of the formula ##STR2## wherein X represents a chlorine, bromine or iodine atom, andR.sup.1, R.sup.2 and R.sup.3 have the meaning given above, is reacted with trimethylsilyl cyanide of the formula, (CH.sub.3).sub.3 SiCN (III), in the presence of a Lewis acid selected from SnCl.sub.4, TiCl.sub.4 and BiCl.sub.3, and, if appropriate, in the presence of a diluent, at a temperature between 10.degree. and 40.degree. C. The tertiary alkyl cyanides of formula (I) can be used as intermediate products, for example for the preparation of known herbicides.
