compactifications and representations of transformation semigroups
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
15 صفحه اولRing Transformation of Oxazolo [3,2-b][1,2,4] Triazines
6-Methyl-2-phenyl-7H-Oxazolo [3,2-b] [1,2,4] triazine (1) undersent ting transformation on treatment with ammonia and primary amines to afford the corresponding imidazol [1,2-b][1,2,4] triazine (2). Treatment of (1) with hydrazine hydrate gave the corresponding 3-aryl-4H-1,2,4- triazino [4,3-b][1,2,4] triazin-8 (1H)-one (3).
متن کاملBis(2,2-dimethyl-2,3-dihydro-1-benzofuran-7-yl) carbonate
The title compound, C(21)H(22)O(5), crystallizes with three mol-ecules in the asymmetric unit. In one mol-ecule, two methyl groups are disordered over two positions with a site occupation factor of 0.72 (2) for the major occupancy site. The benzene rings make dihedral angles of 35.3 (6), 29.7 (6) and 40.6 (7)° in the three molecules.
متن کامل2,2-Dimethyl-2,3-dihydro-1-benzofuran-7-yl N-ethylcarbamate
The title compound, C(13)H(17)NO(3), crystallizes with two independent mol-ecules in the asymmetric unit. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules, forming chains propagaiting in [100]. A weak C-H⋯O inter-action also occurs.
متن کامل7-Chloro-3,3-dimethyl-9-phenyl-1,2,3,4-tetrahydroacridin-1-one
In the title salt, C(21)H(18)ClNO, the quinoline ring system is approximately planar [maximum deviation = 0.035 (2) Å], and forms a dihedral angle of 71.42 (6)° with the attached phenyl ring. The cyclo-hexa-none ring exists in a half-boat conformation. In the crystal packing, C-H⋯O contacts link the mol-ecules into extended supra-molecular chains along the c axis.
