This article describes the design, optimisation and development of a Suzuki cross-coupling protocol mediated by an efficient palladium-encapsulated catalyst (Pd EnCat) under microwave irradiation. The methodology has been used in both batch mode for classical library preparation and in continuous-flow applications furnishing multigram quantities of material. Described is a method that uses direct focused

A new palladium catalyst (DAPCy) made from Pd(OAc)2 and commercially available, inexpensive dicyclohexylamine has been developed for the Suzuki coupling reaction of aryl bromides with boronic acids to give the coupling products in good to high yields. The air-stable catalyst was characterized and well-defined by X-ray crystallography. A catalytic system involving DAPCy in dioxane demonstrates a temperature-dependent
The photoreactions of a number of biphenyl derivatives, in particular nitrobiphenyl derivatives, with cyanideion have been investigated. Photosubstitution by cyanideion has been found to predominate; photoreduction is not observed. In some cases (4-nitrobiphenyl, 4,4′-dinitrobiphenyl, 3-nitrobiphenyl and similar compounds) the behaviour can be rationalized on the basis of analogy to the pattern of

substrates was overcome by holistic optimization of a bimetallic Cu/Pd catalyst system. The combination of a CuI/Me4phen decarboxylation catalyst and a [(MeCN)4Pd](OTf)2/XPhos cross‐coupling catalyst enables the synthesis of biaryls from inexpensive aryl chlorides and potassium benzoates regardless of their substitution pattern.
通过整体优化双金属Cu / Pd催化剂体系,克服了脱羧交叉偶联反应对邻位取代或杂环羧酸酯底物的限制。CuI / Me 4 phen脱羧催化剂和[(MeCN)4 Pd](OTf)2 / XPhos交叉偶联催化剂的组合,无论其取代方式如何,均能从廉价的芳基氯化物和苯甲酸钾合成联芳基。
