COMMUNICATION Direct Csp-Csp cross-coupling of diarylzinc reagents with benzylic, 1°, 2° and 3° alkyl halides**
In this article, we report on the direct Csp-Csp crosscoupling of diarylzinc reagents with benzylic, 1°, 2° and 3° alkyl halides. Under etherate-free conditions, cross-coupling proceeds rapidly at ambient temperature with benzylic, 2° and 3° alkyl halide substrates without addition of an external catalyst. The Csp-Csp cross-coupling has excellent functional group tolerance and products are isol...
متن کاملPalladium-catalyzed homocoupling reactions between two Csp(3)-Csp(3) centers.
[reaction: see text] A novel palladium-catalyzed coupling reaction between two Csp(3)-Csp(3) centers has been investigated. This protocol is initiated by the oxidative addition of an alpha-halo carbonyl compound to a palladium(0) species, followed by the double transmetalation. The key dialkyl palladium intermediate undergoes reductive elimination to form the desired coupling product.
متن کاملUsing CSP To Improve Deterministic 3-SAT
We show how one can use certain deterministic algorithms for higher-value constraint satisfaction problems (CSPs) to speed up deterministic local search for 3SAT. This way, we improve the deterministic worst-case running time for 3-SAT to O(1.439n).
متن کاملArylation of 2-substituted pyridines via Pd-catalyzed decarboxylative cross-coupling reactions of 2-picolinic acid.
The novel palladium-catalyzed decarboxylative cross-coupling reactions of 2-picolinic acid with aryl and heteroaryl bromides including benzenes, naphthalenes, pyridines and quinolines for C-C bond formation have been successfully achieved.
متن کاملPd-catalyzed decarboxylative coupling of propiolic acids: one-pot synthesis of 1,4-disubstituted 1,3-diynes via Sonogashira-homocoupling sequence.
One-pot synthesis of symmetric 1,4-disubstituted 1,3-diynes from iodoarenes and propiolic acid via Sonogashira reaction followed by Pd-catalyzed decarboxylative homocoupling is developed in high yields. Also, this system allows the one-pot synthesis of unsymmetric 1,4-disubstituted 1,3-diynes by cross-coupling of two different 3-substituted propiolic acids.
