4-Ethynyl-N,N-diphenylaniline

4-(Dimethyl­amino)phenyl ethynyl telluride

The title compound, C(10)H(11)NTe, is the first organyl ethynyl telluride, R-Te-C C-H, to be structurally characterized. In the L-shaped mol-ecule, the aryl moiety, viz. Me(2)NC(6)H(4)Te, is almost perpendicular to the Te-C C-H fragment. The Te-Csp(2) bond [2.115 (3) Å] is significantly longer than the Te-Csp bond [2.041 (4) Å]. The Te-C C group is approximately linear [Te-C-C = 178.5 (4)° and ...

4-Ethynyl-N,N-di­phenyl­aniline

The asymmetric unit of the title compound, C20H15N, comprises two crystallographically independent mol-ecules (A and B). In each mol-ecule, the N atom adopts an approximately trigonal planar geometry, lying 0.009 (1) or 0.003 (1) Å from the plane defined by the C atoms of the aromatic substituents to which it is attached. In the crystal, mol-ecules are linked via C-H⋯π inter-actions, forming a ...

4-Ethynyl-2,2,6,6-tetra­methyl-1,2,5,6-tetra­hydro­pyridine N-oxide

The six-membered ring of the title compound, C(11)H(16)NO, has a distorted envelope conformation. The piperidine N atom deviates by 0.128 (1) Å from the plane through its three neighbouring atoms. In the crystal structure, mol-ecules are connected by inter-molecular C(ethyn-yl)-H⋯O contacts to form chains extending in the [10] direction.

Direct Immunosensor Design Based on the Electrochemical Reduction of 4-((4-Nitrophenyl)ethynyl)benzenethiol Monolayers

Quantitative autoradiography of 4'-ethynyl-4-n-[2,3-3H2]propylbicycloorthobenzoate binding to the GABAA receptor complex.

4'-Ethynyl-4-n-[2,3-3H2]propylbicycloorthobenzoate ([3H]EBOB) binding to the GABAA receptor complex was characterized autoradiographically in rat brain and then its binding in human brain was investigated. [3H]EBOB binding was saturable, specific and identified a single population of binding sites. The Kd obtained from saturation studies was 4.59 nM. Picrotoxin produced dose-dependent inhibitio...
