The acetate complex Ru(OAc)2(DiPPF) (2) obtained from Ru(OAc)2(PPh3)2 (1) and 1,1′‐bis(diisopropylphosphino)ferrocene (DiPPF) reacts cleanly with formaldehyde affording Ru(OAc)2(CO)(DiPPF) (3) in high yield. The monocarbonyl complex 3 (0.4‐2 mol %) efficiently catalyzes the N‐alkylation of primary and secondary alkyl and aromatic amines using primary alcohols ROH (R=Et, nPr, nBu, PhCH2) under mild
从Ru(OAc)2(PPh 3)2 (1)和1,1'-双(二异丙基膦基)二茂铁(D i PPF)获得的乙酸盐络合物Ru(OAc)2(D i PPF)(2)与甲醛以高收率提供Ru(OAc)2(CO)(D i PPF)(3)。单羰基络合物 3(0.4-2 mol%)使用伯醇ROH(R = Et,n Pr,n Bu,PhCH 2)在温和的反应条件下(30-100°C),醇/胺的摩尔比为10-100。该一水合物期RuH(OAc)(CO)的形成(d我PPF)(4)已经通过反应观察到3与我PrOH中在网的存在3在RT下通过平衡反应。

precatalyst Pd-PEPPSI-IPr(NMe2)2, in which the IPr ligand was modified by attachment of two dimethylamino groups on to the 4- and 5-positions of the imidazolyl heterocycle, was found to show high catalytic efficiency in the Buchwald-Hartwigamination under mild conditions using Cs2CO3 as a weak base, using a low catalyst loading of 1 mol-%. The protocol is applicable to arylchlorides bearing base-sensitive

Pd‐PEPPSI‐IPent, a recently‐developed N‐heterocyclic carbene (NHC) complex, has been evaluated in amination reactions with secondary amines and it has shown superb reactivity under the most mildly basic reaction conditions. Rate and computationalstudies were conducted to provide insight into the mechanism of the transformation. The IPent catalyst coordinates to the amine much more strongly than the
