We report the preparation and structural analysis of carborane-containing diphenylureas (1a-c and 2a-c). The secondary ureas (1) exist in trans-conformation. In spite of the bulkiness of the carborane cage, the N-methylated ureas (2) exist in cis-conforma

A stepwise synthesis of the donor-acceptor-substituted macrocycle 5,21,37-tris(diethylamino)-13,29,45-trinitro[2.2.2.2.2.2]metacyclophane-1,9,17, 25,33,42-hexayne (1a) from 3,5-bis(3-iodo-5-nitrophenylethynyl)-N,N- diethylaniline (11) and 3,5-bis([3-dieth
