Zusammenfassung

The (n-Bu4N)[M(C6F5)3(CNR)] complexes (M=Pd or Pt; R=p-Tolyl, Me, Cy or t-Bu, prepared from (n-Bu4N)[M(C6F5)3(tht)] (tht = tetrahydrothiophene) and the appropriate isocyanide, RNC, prove to be unreactive towards benzylamine or MeOH. The trans-[Pd(C6F5)2(CNR)2] complexes react slowly with benzylamine to give the corresponding carbene complexes trans-[Pd(C6F5)2{C(NHR)(NHBz)}2], the rate of the reaction decreasing in the order:p-Tolyl > Me > Cy ≫t-Bu (for R=t-Bu the carbene complex cannot be prepared). In the corresponding Pt complexes a marked decrease in reactivity is observed and only the most reactive isonitrile complex (R=p-Tolyl) gives the carbene complex trans-[Pt(C6F5)2{C(NHTolyl-p)(NHBz)}2}. The cis-[M(C6F5)2(CNTolyl)2] complexes do not show any change in reactivity compared to the corresponding trans-complexes, and give cis[M(C6F5)2{C(NHTolyl-p)(NHBz)}2]. © 1984 Verlag Chemie GmbH.
