O-(tert-butyl) Se-phenyl selenocarbonate: A convenient, bench-stable and metal-free precursor of benzeneselenol

A study by our laboratory shows that air, light and moisture stable O-(tert-butyl) Se-phenyl selenocarbonate could be employed as a safer, practical and efficient alternative to generate “in situ” benzeneselenol or benzeneselenolate anion under different and transition metal-free conditions. This procedure seems to be of general application since the nucleophilic selenium species obtained can be trapped by electrophiles such as alkyl halides, epoxides and electron-deficient alkenes and alkynes under different reaction conditions.

The use of an air- and moisture-stable dinuclear PdI complex as an efficient catalyst for the formation of C(sp2)?SeR bonds is here reported. The privileged reactivity of the PdI dimer allows for the direct use of selenolates as nucleophiles in the cross-coupling. Although previous methodologies suffer from catalyst poisoning through the formation of Pd-ate complexes, the mechanistically distinct dinuclear PdI catalyst circumvents this challenge. A wide variety of aryl bromides and iodides were efficiently coupled under relatively mild reaction conditions with broad functional group tolerance. Mechanistic and computational data are presented in support of direct PdI reactivity.

Paragraph 0056; 0065, (2016/11/14)
Disclosed herein is a method of preparing a Cu/Cu2O core-shell copper nanoparticle catalyst having high catalytic activity from [Cu3(BTC)2] and NaBH4 via a simple chemical reduction method. Also disclosed is a method of preparing a chalcogenide compound by using the nanoparticle catalyst as a heterogeneous catalyst in a cross-coupling reaction between a chalcogenide precursor compound and a boron-containing compound. The disclosed cross-coupling reaction is performed via a simple process, and the disclosed nanoparticle catalyst is compatible with various substrates under mild reaction conditions and exhibits excellent recyclability without a reduction in catalytic activity.
