Two new aminophosphines, benzyl-N(Ph2P)(2) and 2-picolyl-N(Ph2P)(2), have been synthesized. Oxidation of the aminophosphines with either hydrogen peroxide, elemental sulfur and selenium gave the corresponding oxides, sulfides and selenides benzyl-N(Ph2P=E) ...
One-pot synthesis of indoles by a palladium-catalyzed annulation of o-haloanilines and aldehydes has been developed. Coupling of o-iodoaniline with aldehyde is realized under mild ligandless conditions [Pd(OAc)2, DABCO, DMF, 85 DegC], whereas X-Phos is fou ...
Methods for the synthesis of dihydroazaphenanthrene fused to macrocycles I [X = CH2, O, Y = (CH2)m, m = 1,2,4,6, n = 1,2] and medium-ring heterocycles II (R1 = H, Me, CH2Ph, etc., R2 = Me, n-Bu, CH2Ph, etc.) as well as 1,4-benzodiazepine-2,5-diones, e.g. I ...
The goal of this thesis is to develop new carbon-carbon bond forming reactions using inexpensive and simple coupling partners like aryl halides (pseudohalides), sulfonyl derivatives, Grignard reagents, alkenes and alkynes with metal catalysis, preferably u ...
Oxidative addition of BrC CC(=O)O-menthyl (1a) to [Pd(PPh3)(4)] affords the alkynyl complex trans-[Br(PPh3)(2)Pd-C CC(=O)O-menthyl] (2a). Subsequent reaction of 2a with trifluoroacetate gives trans-[(F3CCOO)(PPh3)(2)Pd-C CC(=O)O-menthyl] (3a). Reaction of ...
Triple selectivity: Highly substituted indenylamines can be obtained with high enantioselectivity by formal [3+2] additions of aryl ketimines with internal alkynes. These rhodium(I)-catalyzed processes proceed by selective C-H activation of one of the two ...
Polyvinylpyrrolidone stabilized rhodium nanoparticles are highly sol. in hydroxyl-functionalized ionic liqs., providing an effective and highly stable catalytic system. In hydrogenation reactions, excellent results were obtained, and transmission electron ...
A highly efficient palladium-catalyzed synthesis of unsym. substituted 3-(diarylmethylenyl)indolinones from readily accessible starting materials is developed. The domino reaction involves a sequence of intermol. carbopalladation, C-H activation, and C-C b ...
[Pd(PPh3)4]/Cul served as an efficient catalyst for the reaction of three readily available starting materials to give 3-(diarylmethylene)indolin-2-ones, e.g., I, through a sequence of intermol. Sonogashira reaction/intermol. carbopalladation/C-H activatio ...
A series of relatively low-cost ionic liquids, based on the N-butyronitrile pyridinium cation C(3)CNpy, designed to improve catalyst retention, have been prepared and evaluated in Suzuki and Stille coupling reactions. Depending on the nature of the an ...
