Canzoni in concorso nella Palermo di fine secolo
2015
L'articolo si occupa del concorso "per la canzone siciliana" bandito nel 1891 a Palermo da Tina Withaker Scalia con la collaborazione di Giorgio Miclei. Nella prima parte viene presentato un sintetico bilancio dei precedenti non siciliani del concorso nell'Italia post-unitaria, e nella seconda vengono analizzate in dettaglio le due canzoni vincitrici.
Controlling Oxidative Addition and Reductive Elimination at Tin(I) via Hemi-Lability.
2021
We report on the synthesis of a distannyne supported by a pincer ligand bearing pendant amine donors that is capable of reversibly activating E–H bonds at one or both of the tin centres through dissociation of the hemi-labile N–Sn donor/acceptor interactions. This chemistry can be exploited to sequentially (and reversibly) assemble mixed-valence chains of tin atoms of the type ArSn{Sn(Ar)H} n SnAr ( n = 1, 2). The experimentally observed (decreasing) propensity towards chain growth with increasing chain length can be rationalized both thermodynamically and kinetically by the electron-withdrawing properties of the –Sn(Ar)H– backbone units generated via oxidative addition. peerReviewed
