Synthesis of N,N-disubstituted selenoamides by O/Se-exchange with selenium–Lawesson's reagent

Reactions of nitroxides, part 7: Synthesis of novel nitroxide selenoureas

“…The reagent is able to selenate amides and formamides by substitution of the oxygen atom [40,41]. The condensation of dichlorphenylphosphine (7) with magnesium in THF [42][43][44][45][46] yields pentaphenylpentaphospholane [(PhP) 5 , (8)] SCHEME 1 (i) HCOOEt [38] (ii) COCl 2 [38] or ClCOOCCl 3 (diphosgene) (iii) Se, CHCl 3 [39] (iv) (5a-h) HX, benzene (6a,b) HX/NaX.…”

Reactions of nitroxides with sulfur-containing compounds, part IV: Synthesis of novel nitroxide (thio)ureas

“…The formation of the side-product 11 was observed. The structure of 11 was attributed by means of its spectral data, especially by the A 2 B nature of its 31 P{ 1 H} NMR spectrum ( [27,28].…”
