AbstractOrthoamides of alkynecarboxylic acid 15 condense with enolisable β-dicarbonyl compounds and as well with acetophenones to give 3-acryl-1,1-bis(dimethyl-amino)-1,3-butadienes. Some acylbutadienes cyclize affording 2-pyranon-derivatives 33 upon heating with aqueous ethanol. 2H-pyranes are...
AbstractA new carbosilane has been synthesised in one step by hydrosilylation of 1,3-dimethyl-tetravinyldisiloxane with triphenyl silane. The new carbosilane has been characterized by 1D and 2D NMR, MS, and Gel Permeation Chromatography (GPC). The new carbosilane has been spin-coated on silicon...
AbstractThe chemical study of hydroethanolic extracts from different parts of Trichilia prieuriana (Meliaceae) led to the isolation and identification of 22 compounds: 2β,3β,4β-trihydroxypregnan-16-one (1), prieurianin (2), flindissone (3), deoxyflindissone (4), picraquassin E (5), ursolic acid...
AbstractA new cobalt-based coordination polymer (CP), [Co(Htatb)(1,4-bib)]·DMF (1), has been hydrothermally synthesized from CoCl2·6H2O, 4,4′,4′′-s-triazine-2,4,6-tribenzoic acid (H3tatb), and 1,4-bis(1-imidazoly)benzene (1,4-bib). The product has been characterized by IR spectroscopy, elemental...
AbstractPolycrystalline samples of the stannides Ca1.692Pt2Sn3.308, SrPtSn2 and EuAuSn2 were synthesized directly from the elements, using sealed tantalum ampoules as crucible material. The reactions were performed in muffle or induction furnaces. The phase purity of the samples was studied by...
AbstractThe reactions of N-alkyl-N′-picolyl-benzimidazolium bromides or N,N′-dipicolyl-benzimidazolium bromide with silver oxide yielded the silver dicarbene complexes of the type [Ag(NHC)2][AgBr2] 1–4 (NHC = picoline-functionalized benzimidazolin-2-ylidene). The silver complexes 1–4 have been...
