1,8-Bis(silylamido)naphthalene complexes of magnesium and zinc synthesised through alkane elimination reactions
The reactions between magnesium or zinc alkyls and 1,8-bis(triorganosilyl)diaminonaphthalenes afford the 1,8-bis(triorganosilyl)diamidonaphthalene complexes with elimination of alkanes. The reaction between 1,8-C H (NSiMePh H) and one or two equivalents of Mg Bu affords two complexes with differing...

Summary: | The reactions between magnesium or zinc alkyls and 1,8-bis(triorganosilyl)diaminonaphthalenes afford the 1,8-bis(triorganosilyl)diamidonaphthalene complexes with elimination of alkanes. The reaction between 1,8-C
