Hydroformylation of olefins catalyzed by rhodium complexes with phosphinitecalix[4]arenes

Hydroformylation of alkenes with various carbon chain lengths and arylalkenes in the presence of the catalytic system consisting of Rh(acac)(CO)2 and phosphinitecalix[4]arenes was studied. The influence of the P/Rh and substrate/catalyst ratios, temperature, and pressure on the process and the product composition was examined.

Terminal olefins to chromans, isochromans, and pyrans via allylic C-H oxidation

The synthesis of chroman, isochroman, and pyran motifs has been accomplished via a combination of Pd(II)/bis-sulfoxide C-H activation and Lewis acid co-catalysis. A wide range of alcohols are found to be competent nucleophiles for the transformation under uniform conditions (catalyst, solvent, temperature). Mechanistic studies suggest that the reaction proceeds via initial C-H activation followed by a novel inner-sphere functionalization pathway. Consistent with this, the reaction shows reactivity trends orthogonal to those of traditional Pd(0)-catalyzed allylic substitutions.

Synthesis of aromatic aldehydes by aerobic oxidation of hydroaromatic compounds and diarylalkanes using N-hydroxyphthalimide (NHPI) as a key catalyst

Aerobic oxidation of hydroaromatic compounds and diarylalkanes by N-hydroxyphthalimide (NHPI) under mild conditions afforded the corresponding hydroperoxides in high selectivity. Treatment of the resulting hydroperoxides with sulfuric acid followed by neutralization by a base resulted in phenol and aromatic aldehydes in high selectivity. This method provides a convenient synthetic route to aldehydes involving an aromatic moiety.
