One-pot reactions leading to highly functionalized coumarins have been developed via a Pd(II)-catalyzed dehydrogenation-oxidative Heck-cyclization process.

An efficient synthesis of tri-O-methylated resveratrol is presented using an advanced Heck reaction promoted by Pd(dba)(2) in the presence of P(t-Bu)(3).

Carbon-carbon cross-coupling reactions are essential synthetic tools for synthesizing polymers, natural products, agrochemicals, and pharmaceuticals. Therefore, new catalysts that function with greater efficiency functional group tolerance being researched. We have prepared ferrocenylimine monodentate N P donor ligands N^N N^P bidentate chelating (L1 to L4) employed in stabilizing palladium ion...

We present software for spherical harmonic analysis (SHA) and spherical harmonic synthesis (SHS), which can be used for essentially arbitrary degrees and all co-latitudes in the interval (0◦, 180◦). The routines use extended-range floating-point arithmetic, in particular for the computation of the associated Legendre functions. The price to be paid is an increased computation time; for degree 3...
