Abstract A combined theoretical and experimental study on the formation and reactivity of a P ‐OTEMP (P‐bound TEMPO (TEMPO=2,2,6,6‐tetramethyl‐piperidin‐1‐oxyl)) substituted 1,3,2‐diazaphospholane W(CO) 5 complex is presented, including DFT‐based mechanistic details. The complex possesses a thermally labile O−N bond that cleaves homolytically yielding the transient 1,3,2‐diazaphospholane‐2‐oxyl complex [(CO) 5 W(R 2 PO . )], which acts as a radical initiator for styrene polymerization under ambient conditions.
