Synthesis, crystal structure and homogeneous catalytic activity towards ethylene polymerisation of the spirocyclic chromium(II) 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.
