Synthesis, crystal structure and homogeneous catalytic activity towards ethylene polymerisation of the spirocyclic chromium(<scp>II</scp>) siloxane [C[graphic ommitted])-µ-Na(thf)₂}₂](thf = tetrahydrofuran)

Abstract

The chromium(II) compound [C[graphic ommitted])-µ-Na(thf)2}2]1 has been isolated and structurally characterised; in combination with trimethylaluminium, it is a precatalyst for the polymerisation of ethene to linear polyethylene.
