Structural diversity in the products formed by the reactions of 2-arylselanyl pyridine derivatives and dihalogens

The reactivity of the 2-arylselanyl pyridine derivatives L1-L4 towards dihalogens X2 (X = I, Br) and interhalogens IX (X = Cl, Br) was studied in CHCl3 or CH3CN. The solid products obtained were structurally characterized and their nature points out the preference for CT spoke adducts and for seesaw insertion adducts to be formed at the N-donor and Se-donor site, respectively. DFT calculations were performed to provide a rationale for the structural diversity observed in the products obtained.

Copper-catalyzed: Ipso -selenation of aromatic carboxylic acids

The copper-catalyzed decarboxylative selenation of aromatic carboxylic acids with diselenide is reported. This transformation tolerated a diverse set of functional groups on the substrates, including pentafluorobenzoic acid and heteroaromatic acids, delivering diaryl and methyl aryl selenides in good to excellent yields. Mechanistic studies indicated that the copper catalyst is essential in the activation of the Se-Se bond and the decarboxylation of aromatic acids. The utility of the products has been demonstrated in the facile synthesis of 10H-phenoselenazine and 11-methyldibenzo-(b,f)-1,4-selenazepine.

THE SYNTHESIS OF BIS(PHENYLSELENENYL), BIS(ALKYELSELENENYL)PYRIDINES AND OF PYRIDYLSELENOLATE ANIONS

The reactions of several dihalogenopyridines with PhSeNa or MeSeLi in DMF afforded the monosubstitution products in good yields.With excess PhSeNa the bis(phenylselenenyl)pyridines were easily obtained, Whereas with excess MeSeLi the initially formed halo
