3-difunctionalization of terminal alkenes using 1,1-disubstituted alkenyl nonaflates and arylboronic acid coupling partners is reported. This transformation affords allylic arene products that are difficult to selectively access using traditional Heck cross-coupling methodologies. The evaluation of seldom employed 1,1-disubstituted alkenyl nonaflate coupling partners led to the elucidation of subtle mechanistic
Alkenyl triflates in combination with Co(acac)(3) as a catalyst were found to be excellent coupling partners of alkynyl Grignardreagents, where no special additives (even a phosphine ligand) but a common solvent, THF, are required to obtain variously substituted enynes.
The present invention provides compounds and pharmaceutical compositions that are selective antagonists of A
2B
adenosine receptors (ARs). These compounds and compositions are useful as pharmaceutical agents.

Disclosed herein are a reaction method and a production method of an organic compound which are capable of achieving high reaction selectivity according to the purpose and a high production rate of a target substance. The methods include at least two fluids, wherein at least one kind of the fluids is a fluid containing at least one organic compound and at least one kind of the fluids other than the above fluid is a fluid containing at least one reactant in the form of a liquid or solution, and the respective fluids join together in a thin film fluid foamed between processing surfaces arranged to be opposite to each other so as to be able to approach to and separate from each other, at least one of which rotates relative to the other, whereby an organic reaction is performed in the thin film fluid.
