The solvents o-, m-, p-xylene, p-dichlorobenzene, 1,2,4-trichlorobenzene, and naphthalene were calibrated as condensates used in the thermoporosimetry technique. Exponential relationships were found connecting the pore radii R(p) (in nm) and the freezing-point depression of the swelling solvent deltaT (in degrees C) on the one hand and the apparent energy of crystallization W(a) (in J cm(-3)) a...

THE present work was undertaken as a preliminary step in the investigation of the experimental haemoglobinuria described by Callow and Hele [1927]. These workers found that p-bromoand p-chloro-phenylmercapturic acids, whether given by the mouth or subcutaneously, cause a transient haemoglobinuria in the dog. An attempt was made to find a small animal which would show a similar response to dosag...

Hydrocarbon-soluble β-diketiminato phenylcalcium derivatives, which display various modes of Ca−μ2-Ph−Ca bridging, are accessible from reactions Ph2Hg and [(BDI)CaH]2. Although the resultant compounds inert toward C−H bonds benzene, they yield selective uncatalyzed biaryl formation when reacted with readily available aryl bromides.

The title compound, C(13)H(18)O(4), is an inter-mediate product in the synthesis of quinazoline derivatives. Crystal structure analysis shows that the benzene-butoxy C(ar)-O-C-C torsion angle is 175.3 (2)° and that the benzene-methoxycarbonyl C(ar)-C-O-C torsion angle is 175.2 (2)°. Torsion angles close to 180° indicate that the molecule is almost planar.

Among the aromatic ketones, aceto phenone and its various substituted derivatives have been studied since early 20 century. This ketone can perform the self condensation reaction and produces trimmer having an aromat ic ring of 1,3,5-triphenyl benzene (T.P.B) with general fo rmula of C24H18. In this research, the compounds 1,3,5-triphenyl benzene and 1,3,5-tris (2-naphthyl) benzene are synthesi...

The aromatic polyketones 3a-d are versatile compounds for the synthesis of the multi-1,2,3-selenadiazole aromatic derivatives 1a-d. The preparation starts with the reaction between the multi-bromomethylene benzene derivatives 2a-d and 4-hydroxy- acetophenone to give compounds 3a-d which are transformed through the reaction with semicarbazide hydrochloride or ethyl hydrazine carboxylate into the...
