An approach to novel P -functional chloroformylphosphane complexes is described using the synthetic potential of lithium/halogeno phosphinidenoid tungsten(0) complexes. Similarly to transition-metal-free chloroformylphosphanes, the obtained complexes tend to eliminate CO via P–C bond cleavage to give the corresponding P -chlorophosphane complex derivatives. Nevertheless, this method allowed the isolation of the first complex derivatives, which will open new synthetic perspectives in organophosphorus chemistry.

Synthesis and Rearrangement of P -Nitroxyl-Substituted P^III and P^V Phosphanes: A Combined Experimental and Theoretical Case Study

Chemistry - A European Journal (2016)

Tobias Heurich Zheng‐Wang Qu Senada Nožinović Gregor Schnakenburg Hideto Matsuoka

Low-temperature generation of P-nitroxyl phosphane 2 (Ph2POTEMP), which was obtained by the reaction of Ph2PH (1) with two equivalents of TEMPO, is presented. Upon warming, phosphane 2 decomposed to give P-nitroxyl phosphane P-oxide 3 (Ph2P(O)OTEMP) as one of the final products. This facile synthetic protocol also enabled access to P-sulfide and P-borane derivatives 7 and 13, respectively, by using Ph2P(S)H (6) or Ph2P(BH3)H (11) and TEMPO. Phosphane sulfide 7 revealed a rearrangement to phosphane oxide 8 (Ph2P(O)STEMP) in CDCl3 at ambient temperature, whereas in THF, thermal decomposition of sulfide 7 yielded salt 10 ([TEMP-H2][Ph2P(S)O]). As well as EPR and detailed NMR kinetic studies, indepth theoretical studies provided an insight into the reaction pathways and spin-density distributions of the reactive intermediates.

Chemistry of Thermally Generated Transient Phosphanoxyl Complexes

Organometallics (2017)

Tobias Heurich Zheng‐Wang Qu Gregor Schnakenburg Yaser NejatyJahromy Olav Schiemann

Investigations on the reactivity of the transiently formed phosphanoxyl complex [(CO)5W(Ph2PO•)], thermally generated from [(CO)5W(Ph2PO-TEMP)] in toluene, is presented. Apart from self-reactions, trapping of this radical complex was achieved using group 14 hydrides Ph3EH (E = Si, Ge, Sn), leading to new phosphane complexes possessing a P–O–EPh3 bonding motif and the corresponding TEMP-H as byproduct. Reaction pathways, derived from DFT calculations, clearly revealed the intermediacy of various open-shell complexes; EPR measurements showed the presence of radicals, but unfortunately interpretation was not achieved.
