Three isoelectronic analogues of pyrido[2,1-a]isoindole have been found to undergo a facile 1,1-hydroboration with HBMes2 borane, which provides a new and convenient method for the synthesis of B,N-heterocycles 1a-3a in high yields. Compounds 1a-3a can undergo photoelimination upon irradiation at 300 nm, generating heterocycle-fused B,N-naphthalene molecules 1b-3b, which display distinct yellow-green and blue fluorescent colors, respectively. Compound 1a undergoes thermal elimination, producing 1b at 280°C, while compound 2a only undergoes partial elimination, forming 2b at 320°C. Compound 3a is thermally stable up to 320°C.

Iridium-catalyzed acceptorless dehydrogenative coupling of tertiary amines and arylamines has been developed. A number of benzimidazoles were prepared in good yields. An iridium-mediated C-H activation mechanism is suggested. This finding represents a novel strategy for the synthesis of benzimidazoles.
Dual Catalysis in Domino N-Benzylation/Intramolecular C-H Arylation: Regio- and Chemoselective Synthesis of Annelated Nitrogen Heterocycles
Laha, Joydev K.,Dayal, Neetu,Singh, Swati,Bhimpuria, Rohan
, p. 5469 - 5475 (2014/10/15)
A general method has been developed for the synthesis of fused nitrogen heterocycles by using a domino N-benzylation/C-H arylation reaction sequence. The details and yields of the domino process were compared with those of the two-step literature protocol
