The mol-ecules of N-(3-tert-butyl-1-phenyl-1H-pyrazol-5-yl)-2-chloro-N-(4- methoxy-benz-yl)acetamide, C23H26ClN3O 2, are linked into a chain of edge-fused centrosymmetric rings by a combination of one C - H...O hydrogen bond and one C - H...π(arene) hydrogen bond. In N-(3-tert-butyl-1-phenyl-1H-pyrazol-5-yl)-2-chloro-N-(4- chloro-benz-yl)acetamide, C22H23Cl2N 3O, a combination of one C - H...O hydrogen bond and two C - H...π(arene) hydrogen bonds, which utilize different aryl rings as the acceptors, link the mol-ecules into sheets. The mol-ecules of S-[N-(3-tert-butyl-1-phenyl-1H-pyrazol-5-yl)-N-(4-methyl-benz-yl)carbamo-yl] methyl O-ethyl carbonodithio-ate, C26H31N 3O2S2, are also linked into sheets, now by a combination of two C - H...O hydrogen bonds, both of which utilize the amide O atom as the acceptor, and two C - H...π(arene) hydrogen bonds, which utilize different aryl groups as the acceptors.

Using a tin-free strategy, novel 4H-benzo[f]pyrazolo[1,5-a][1,3]diazepin- 5(6H)-ones were synthesized in acceptable yields via intra-molecular alkylation over a benzene ring, of α-alkylcarbonyl radicals generated from ethyl pyrazolylbenzylaminoxanthates,
