6,7-Diphenyl-5-thia-7-azaspiro[2.6]nonan-8-one
The asymmetric unit of the title compound, C19H19NOS, contains two independent mol-ecules (A and B), in both of which the 1,3-thia-zepan-4-one ring adopts a chair-type conformation. The dihedral angles between the two phenyl rings are 65.28 (8) and 60.31 (9)° for mol-ecules A and B, respectively. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions, resulting in a three-dimensional...

In this study, a novel method to synthesis of 1,3,5,7-tetraacetyl octahydro-1,3,5,7-tetraazocine or 1,3,5,7-tetraacetyl-1,3,5,7-tetraazacyclooctane (TAT) was used through acetolysis of 3,7-diacetyl-1,3,5,7-tetraazabicyclo-[3.3.1]nonane (DAPT) with acetic anhydride in the presence of sodium acetate as catalyst. Optimized reaction conditions were obtained by changing temperature, time and startin...

46 There is a significant body of research examining the intelligibility of sinusoidal replicas of 47 natural speech. Discussion has followed about what the sinewave speech phenomenon might 48 imply about the mechanisms underlying phonetic recognition. However, most of this work has 49 been conducted using sentence material, making it unclear what the contributions are of 50 listeners’ use of l...

In the title compound, C(19)H(22)N(2)O, the diazepine ring adopts a distorted chair conformation. One of the N-H groups forms an inter-molecular N-H⋯O hydrogen bond generating an R(2) (2)(8) graph-set motif. The other N-H group does not form a hydrogen bond.
