Vinylation of a Secondary Amine Core with Calcium Carbide for Efficient Post-Modification and Access to Polymeric Materials

Molecules, 2018
We developed a simple and efficient strategy to access N-vinyl secondary amines of various naturally occurring materials using readily available solid acetylene reagents (calcium carbide, KF, and KOH).

Polystyrene Nanocomposites based on Carbazole-Containing Surfactants [PDF]

, 2005
New organically-modified clays containing a carbazole unit were prepared and the number of long alkyl chains on the surfactant was varied. The clay was used to prepare polystyrene nanocomposites by both bulk polymerization and melt blending.

9-Benzyl-9H-carbazole [PDF]

Acta Crystallographica Section E Structure Reports Online, 2010
The asymmetric unit of the title compound, C(19)H(15)N, contains two crystallographically independent mol-ecules. In both mol-ecules, the planar carbazole moieties [maximum deviations = 0.037 (4) and 0.042 (3) Å] are oriented with respect to the adjacent benzene rings, at dihedral angles of 85.29 (8) and 89.89 (7)°, respectively.

3-(Trimethylsilylethynyl)carbazole

Acta Crystallographica Section E Structure Reports Online, 2003
The title compound, [Si(CH3)3(C14H8N)] is a TMS-protected mono-alkyne. It is used as a model species for platinum σ-acetyl­ide compounds of which it is a precursor. Such compounds are of interest due to the extended π-conjugation through the hetero-aromatic linker unit in the backbone.
