The organic chemistry of dinitrogen

Recent Advances in the Chemistry of Dinitrogen Complexes

“…As for the older works, readers can refer to several comprehensive reviews which appeared previously.10-13 More reviews are also available, which cover some limited areas in this chemistry. [14][15][16][17][18][19][20][21] II. Advances in Syntheses and Structures of…”

N‐Arylation and N,N‐Dibenzylation of Coordinated N2 with Organic Halides; Differences in the Reactivity of trans‐[Mo(N2)2(Me8[16]aneS4)] and Its Phosphane Analogues

“…' I A variety of organic compounds such as RX (R = alkyl, acyl) and acid anhydrides have been found to react with Moo-, W'-, and Re'-N,-phosphane complexes to give organo-diazenido and/or -hydrazido complexes. So far, however, no N-arylation or N-benzylation of coordinated N, with aryIX and PhCH,X has been achieved, [2][3] with the corresponding organic halides to give aryldiazenido and dibenzylhydrazido complexes, respectively. To clarify the difference in reactivity between 1 and the phosphane analogues further, liberation of NH, and acetone azine from 1 were also examined.…”

A tungsten complex containing a highly delocalized metal–ligand system

“…The cationic dichlorodiazomethane complex trans-[BrW-(dppe) 2 (N 2 CCl 2 )] + [dppe is 1,2-bis(diphenylphosphino)ethane], (I), is readily obtained from trans-W(dppe) 2 (N 2 ) 2 via the hydrazido(2À) complex trans-[BrW(dppe) 2 (NNH 2 )] + , and undergoes facile replacement of one or both chloro substituents by a wide range of nitrogen-and oxygen-based nucleophiles (Colquhoun, 1984). We report here the first example of such a reaction involving a carbon-centred nucleophile, (triphenylphosphonio)cyclopentadienide, which (probably for steric reasons) replaces just one of the two chloro substituents at C to give trans-[BrW(dppe) 2 {N 2 C-(Cl)(C 5 H 3 PPh 3 )}] + , isolated as the title hexafluorophosphate salt, (II).…”
