Synthesis and crystal structure of Cu(I) π-complexes with N-allyl-5-amino-1-phenyl-1H-1,2,3-triazole-4-carboxamide [Cu(C12H13N5O)(NO3)] · 0.5H2O and [Cu(C12H13N5O)(CF3COOH)]

Synthesis and synthetic applications of cyanoacetamides

“…Subjecting the active methylene precursor 3s to the aforementioned reaction using α-halocarbonyl reagents 33b and 29c afforded the functionalized thiophene derivatives 36 through the intermediacy of the potassium sulfide salt 35 (Scheme 15). 25…”

“…The reaction of compound 3s with phenyl isothiocyanate 22a in 1,4-dioxane containing trimethylamine is assumed to involve a nucleophilic attack of the amidic NH in 3 on the C=S of the isocyanate to give the addition adduct 239 which undergoes 1,6-dipolar cyclization to form 2-thioxo-6-pyrimidone derivative 240 (Scheme 102). 25…”

“…Cyanoacetamide 3s was reacted with salicylaldehyde 13aa to yield the coumarin product 301 (Scheme 138). 25…”

“…addition of activated methylene in the cyanoacetamides 3aw-fv to several arylidenmalononitrile 175 in ethanol42 or pyridine4 containing piperidine at reflux yielded pyrido[1,2-a]thieno[3,2-e]pyrimidine derivatives 358a-v via the intermediacy of 354-357 (Scheme 165, Table58). compound 3s in 1,4-dioxane containing triethylamine affected cyclization into the tetrahydrobenzo[4,5]thieno[2,3-b]pyridine derivative 361 (Scheme 167) 25. reaction of methyl o-(azidomethyl)benzoates 367a-c with 2-cyanoacetamides to produce triazolo[1,5b][2,4]benzodiazepines 368a-j was achieved by the action of either MeONa, t-BuOK, EtONa, or KOH (Scheme 170, Table61) 153.…”

Oxygen activation by copper camphor complexes

“…Copper compounds play a role in areas so diverse as catalysis, [1][2][3][4][5][6][7][8] biological applications, [9][10][11][12][13][14][15] food and materials related processing, 16,17 waste treatment 18 or agriculture (e.g. CuSO 4 in vineyards).…”
