Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 1,2-Bis(diphenylphosphino)ethane, is researched, Molecular C26H24P2, CAS is 1663-45-2, about Homoleptic versus heteroleptic trinuclear systems with mixed L-cysteinate and D-penicillaminate regulated by a diphosphine linker.HPLC of Formula: 1663-45-2.
Controlled generation of homoleptic vs. heteroleptic AuI2M (M = NiII, ZnII) trinuclear complexes, which is achieved by a slight change in the diphosphine P^P linker of digold(I) metalloligands, [Au2(P^P)(D-pen)2]2- (L1P^P; D-pen = D-penicillaminate) and [Au2(P^P)(L-cys)2]2- (L2P^P; L-cys = L-cysteinate), is reported. The reactions of a 1 : 1 mixture of L1dppm and L2dppm (dppm = bis(diphenylphosphino)methane) with M = NiII, ZnII gave the homoleptic AuI2M complexes, [M(L1dppm)] and [M(L2dppm)], which co-crystallized to form [M(L1dppm)]·[M(L2dppm)] (1M). Similar reactions using L1dppe and L2dppe (dppe = bis(diphenylphosphino)ethane), instead of L1dppm and L2dppm, led to the selective production and crystallization of the heteroleptic AuI2M complex, [M(L3dppe)] (2M; L3dppe = [Au2(dppe)(L-cys)(D-pen)]2-), accompanied by the scrambling of L1dppe and L2dppe. The homoleptic 1M and the heteroleptic 2M showed different absorption (green vs. blue) and emission (yellow vs. orange) colors for M = NiII and ZnII, resp.
