Photochromic 2h-chromenes annelated at c5-c6 and their methods of preparation

Described herein are C5-C6 annelated naphthopyrans that possess at least one electron-withdrawing group. The compounds possess desirable properties such as increased fading kinetics. Also described herein are new methods for synthesizing 2H-chromenes annelated at C5-C6. The methods involve less stringent reaction conditions as well as provide increased reaction yields. The methods permit the synthesis of a wide variety of substituted naphthopyrans that can be temperature sensitive, which was not possible with previous synthetic routes.

Oxalyl chloride as carbonyl synthon in Pd-catalyzed carbonylations of triarylbismuth and triarylindium organometallic nucleophiles

Oxalyl chloride has been demonstrated to function as C1 carbonyl synthon in the carbonylations of triarylbismuth and triarylindium nucleophiles under palladium-catalyzed conditions. All the three aryl groups from both bismuth and indium reagents participated in carbonylative couplings to afford the corresponding functionalized ketones in high yields. This study also disclosed a novel utilization of oxalyl chloride as facile alternative source of CO for carbonylations under palladium catalysis.
