چکیده
Multicomponent reactions involving azines (4-methylpyridine, isoquinoline and N-methyl imidazole) and acetylenic ester were undertaken in the presence of CH compound such as 2-furoyl trifluoroacetone(4,4,4-trifluoro-1-thiophen-2-yl-butan-1,3-dione) to generate enaminoesters as stable 1,4-diionic compounds in high yields.

Synthesis, properties and surface self-assembly of a pentanuclear cluster based on the new π-conjugated TTF-triazole ligand
The new π-extended redox-active ligand with both TTF and triazole units, 6-(4,5-bis(propylthio)-1,3-dithiol-2-ylidene)-1H-[1,3]dithiolo[4',5':4,5]benzo [1,2-d] [1-3]triazole, has been successfully prepared. Based on the versatile ligand and Cu(tta)2 precursors (tta(-) = 4,4,4-trifluoro-1-(thiophen-2-yl)butane-1,3-dione), a TTF-based pentanuclear Cu(II) cluster (Cu5(tta)4(TTFN3)6) is synthesized...

A green and convenient protocol is described for the preparation of E-1-(alkylamino)-3- (1,3-dioxoisoindolin-2-yl)-2-methyl-1-oxopropan-2-yl viaone-pot three-component reaction between 2-(2-oxopropyl)isoindoline-1,3-dione, an alkyl isocyanide and an E-cinnamic acid in water at room temperature. The methods used to follow the reactions are TLC and NMR, which indicated that there is no side produ...
متن کاملThe synthesis of 1-(4-triethoxysilyl)phenyl)-4,4,4-trifluoro-1,3-butanedione, a novel trialkoxysilane monomer for the preparation of functionalized sol-gel matrix materials.
The title compound, 1-(4-triethoxysilyl)phenyl)-4,4,4-trifluoro-1,3-butanedione, was synthesized in a three-step sequence starting from 2-(4-bromophenyl)propene. Containing both a trialkoxysilyl and a substituted 1,3-butanedione functional grouping within its structure, this new silane is a viable starting material for the preparation of functionalized sol-gel materials.

The title salt, C(3)H(10)N(+)·C(14)H(8)F(3)O(2) (-), constitutes the first organic crystal containing a residue of 4,4,4-trifluoro-1-(naphthalen-2-yl)butane-1,3-dione. The terminal -CF(3) group is disordered over two locations [occupancy ratio = 0.830 (7):0.170 (7)]. Bond delocalization involving the two carbonyl groups and the α-carbon was observed. The crystal packing is mediated by several s...
