We have developed a programmable and diversity-oriented synthetic scheme for tetrasubstituted olefins through a site-selective and sequential assembly of pi-components onto a C=C core of vinyl 2-pyrimidyl sulfide. Noteworthy features are that (i) all components assembled stem from readily available

The amination of aryl halides in the presence of inexpensive and air-stable alkali metal hydroxide bases and Pd[P(t-Bu)3]2 as catalyst gave arylamines in high yields. The reactions were conducted with a catalytic amount of cetyltrimethylammonium bromide as phase-transfer agent and

The palladium-catalyzed Suzuki-Miyaura cross-coupling on a multisubstituted sp(3)-carbon in 1,1-diborylalkanes was achieved at room temperature. The generation of a monoborate intermediate by virtue of the adjacent B atom could result in the chemoselective coupling reaction under ambient conditions.

Procedures for Transition-Metal-Catalyzed Cross-Coupling Reactions in Water at Room Temperature using TPGS-750-M

TPGS-750-M, a second generation surfactant, is useful for room temperature, palladium and ruthenium-catalyzed reactions in water. Reactions include the Heck reaction, Suzuki-Miyaura reaction, Sonogashira reaction, Buchwald-Hartwig amination reaction, Negishi reaction, and olefin metathesis.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
