General description

tert-butyl peroxybenzoate (TBPB)-mediated 2-isocyanobiaryl insertion with 1,4-dioxane has been reported.

Application

Luperox was employed as polymerization and cross-linking catalyst. It was also was employed as initiator during:
  • grafting of 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO)-4-oxyacetamido-(3 propyltriethoxysilane) to poly(ethylene co-octene)
  • preparation of conformal poly(cyclohexyl methacrylate) thin films via initiated chemical vapor deposition
