چکیده
Ferric chloride induced dehydrodimerization of l,2 ,3 ,4 -te trah yd ro-9 //-carb azole (1) gives pro duct 6 , the structure of which was established on the basis of its spectroscopic properties. The *H and 13C chemical shifts of the arom atic part of 1 , as well as of 4a-m eth yl-2 ,3 ,4 ,4a-tetrah yd ro-l Hcarbazole (7 a ) and 4a-ph enyl-2 ,3 ,4 ,4a-tetrahyd ro-l//-carb azole (7b ) have also been securely assigned.
