Bis(μ-N,N′-η2-N,O-η2-N′,O′-di(o-methoxyphenyl)formamidinato)disilver(I): an interesting coordination geometry for silver(I) and room temperature fluorescence

Abstract Reported here are the synthesis, structural and spectroscopic characterization of the title disilver compound, which provides the first example of room temperature fluorescence from a d10–d10 compound. In addition to confirmation of the dinuclear nature of the compound, X-ray crystallographic analysis reveals an N2O2 (distorted) tetrahedral coordination for each silver(I) center.

Dichotomous Reactivity of PCl5 and PBr5 Toward Cyclic Ketones: A One-Step Preparation of 1,1,2-Trichlorocycloalkanes

Abstract Small-ring cyclic ketones react with excess PCl5 in CCl4 (reflux, 1-3 d) to give the corresponding 1,1,2-trichlorocycloalkanes, but react with PBr5 to give ketones brominated in the α-positions.
