developed for the formal nucleophilic silyl substitution of aryl halides with silyllithium or silylpotassium reagents. Dimethylphenylsilyllithium reacted with various aryl halides to form the corresponding arylsilanes in moderate to good yields with concomitant formation of the disilanes under the optimized reaction conditions. Mechanistic studies indicated that this silyl substitution reaction progresses

Palladium-catalysed silylation of aryliodides with electron-withdrawing groups was efficiently achieved using pyridine and lithium chloride as additives and conducting the reaction at room temperature. Functionalized aryl[2-(hydroxymethyl)phenyl]dimethylsilanes were also prepared by palladium-catalysed reaction using THP-protected [2-(hydroxymethyl)phenyl]dimethylsilane as a silylating agent followed
Fungicidal heterocyclic silyl compounds of the general formula ##STR1## have been discovered wherein Het is a six membered heterocyclic moiety; R is hydrogen or a trisubstituted silyl group; R.sup.1, R.sup.2 and R.sup.3 are independently selected from substituted or unsubstituted alkyl, alkenyl, alkynyl, aryl, arylalkyl or pyridyl groups; m is 0 or 1 and n is zero, one or two.
