Synthetic method of diarylmethanes

The invention discloses a synthetic method of diarylmethanes. The method is characterized in that benzyl pseudohalide and aromatic boric acid are reacted in an organic solvent under alkaline condition. The method employs easily available raw materials, conversion is realized under effect of no transition metal catalysis, water-free and oxygen-free are not required, Lewis acid catalysis is not required, the method has wide substrate universality, and various substituted diarylmethanes can be synthesized by the method.

Coupling of arylboronic acids with benzyl halides or mesylates without adding transition metal catalysts

We report herein a transition-metal-free coupling reaction of arylboronic acids with benzyl halides and mesylates for the construction of C(sp2)[sbnd]C(sp3) bonds. A unique feature of this coupling reaction is the formation regioisomers in some cases. Mechanistic studies suggest that this reaction may proceed via an unprecedented Friedel–Crafts-type reaction pathway under base conditions with the assistance of boronic acid moiety.

Synthesis of diarylmethanes through palladium-catalyzed coupling of benzylic phosphates with arylsilanes

An efficient approach to the benzylation of arenes has been developed. The reactions described provide straightforward access to diarylmethanes through Pd-catalyzed coupling of benzylic phosphates with arylsilanes in good to excellent yields. The reaction tolerates a wide range of functionalities such as halide, alkoxyl, and nitro groups.

Suzuki-miyaura cross-couplings mediated by trans-PdBr(N-Succ)(PPh 3)2: A convenient synthetic method for diarylmethanes and aryl(heteroaryl)- methanes

Diarylmethanes can be accessed efficiently by Suzuki-Miyaura cross-couplings of arylboronic acids with benzyl halides mediated by trans-PdBr(N-Succ) (PPh3)2. The methodology can be applied to the synthesis of aryl(heteroaryl)methanes. Georg Thieme Verlag Stuttgart New York.

One-pot dual substitutions of bromobenzyl chloride, 2-chloromethyl-6- halogenoimidazo[1,2-a]pyridine and -[1,2-b]pyridazine by Suzuki-Miyaura cross-coupling reactions

A very simple, mild and inexpensive palladium-catalyzed cross-coupling of (hetero)arylboronic acids with benzylic halides occurs in good yield. This method was successfully expanded to two heterocyclic electrophiles and allowed onepot dual substitutions of bromobenzyl chloride, 2-chloromethyl-6- halogenoimidazo[1,2-a]pyridine or -[1,2-b]pyridazine, leading to numerous new unsymmetrical methylenelinked biaryl systems.

N-tosyloxycarbamates as reagents in rhodium-catalyzed C-H amination reactions

Metal nitrenes for use in C-H insertion reactions were obtained from N-tosyloxycarbamates in the presence of an inorganic base and a rhodium(II) dimer complex catalyst. The C-H amination reaction proceeds smoothly, and the potassium tosylate that forms as a byproduct is easily removed by filtration or an aqueous workup. This new methodology allows the amination of ethereal, benzylic, tertiary, secondary, and even primary C-H bonds. The intramolecular reaction provides an interesting route to various substituted oxazolidinones, whereas the intermolecular reaction gives trichloroethoxycarbonyl-protected amines that can be isolated with moderate to excellent yields and that cleave easily to produce the corresponding free amine. The development, scope, and limitations of the reactions are discussed herein. Isotopic effects and the electronic nature of the transition state are used to discuss the mechanism of the reaction.

Simple palladium(II) precatalyst for suzuki-miyaura couplings: Efficient reactions of benzylic, aryl, heteroaryl, and vinyl coupling partners

trans-PdBr(N-Succ)(PPh3)2 (1) is a universally effective precatalyst for Suzuki-Miyaura cross-couplings of benzylic halides with aryl- or heteroarylboronic acids. Substituted aryl halides and halogenated cyclic enones can be cross-coupled with aryl- or vinylboronic acids in excellent yields. Catalyst recycling is also demonstrated.

Suzuki-miyaura cross-coupling reactions of benzyl halides with potassium aryltrifluoroborates

(Chemical Equation Presented) The palladium-catalyzed cross-coupling of potassium aryltrifluoroborates with benzylic halides occurs in good yield with high functional group tolerance. The increased stability of potassium aryltrifluoroborates compared to other boron coupling partners makes this an effective route to functionalized methylene-linked biaryl systems.

Air-stable, phosphine-free anionic palladacyclopentadienyl catalysts: Remarkable halide and pseudohalide effects in Stille coupling

The Stille cross-coupling of allylic and benzyl bromides is shown to proceed efficiently using phosphine-free dinuclear anionic palladacyclopentadienyl catalysts possessing bridging (N,O)-imidate ligands. The type of bridging anion influences the catalytic activity considerably. Halide anions such as chloride, bromide or iodide also influence the catalytic activity but to a far lesser extent than the pseudohalide imidate anions (from succinimide or phthalimide). A Baldwin-type cooperative effect is seen with 7a using CuI as a co-catalyst, in the presence of two equivalents of CsF in DMF at 40°C. In toluene, these additives slow down substrate turnover.

Suzuki-Miyaura cross-coupling of benzylic phosphates with arylboronic acids

(Chemical Equation Presented) Suzuki-Miyaura cross-coupling of benzylic phosphates with arylboronic acids was investigated. Optimum conditions employed the simple catalytic system of palladium(II) acetate (1 mol %) and triphenylphosphine (4 mol %) with either potassium phosphate or potassium carbonate as the base and toluene as the solvent at 90°C. Using the developed conditions, a series of structurally diverse diarylmethanes were prepared.
