The reactivity of N-amidinothiourea (1) as an electron donor towards several electron-accepting functional groups via electron-donor-acceptor (EDA) interaction has been studied. Thus on treatment of 1 with either 1,1,2,2-tetracyanoethylene (TCNE, 2), 2,3-dicyano-1,4-naphthoquinone (DCNQ, 4), 2,3,5,6-tetrabromo-1,4-benzoquinone (BHL-p, 6), 2,3-dichloro-1,4-naphthoquinone (DCHNQ, 8), 2,3,5,6-tetr...

The molecule of the title compound, C(31)H(16)F(6)N(2)O(4), consists of two phthalimide units linked by a [bis-(trifluoro-meth-yl)methyl-ene]di-p-phenyl-ene bridge, with the two halves of the mol-ecule related to each other by a twofold rotation axis. The dihedral angle between the planes of the two central benzene rings is 70.5 (3)°. The terminal isoindole groups are approximately planar, with...

The title complex, [Er(C(32)H(16)N(8))(C(5)H(7)O(2))(C(12)H(8)N(2))], possesses a mirror plane and the asymmetric unit is half of the mol-ecule. The Er(III) cation, lying on the mirror plane, is eight-coordinated by two O atoms from acetyl-acetone, two N (N(phen)) atoms from 1,10-phenanthroline and four isoindole N (N(iso)) atoms from the phthalocyanine ligand in an anti-prismatic geometry. The...

A Fischer indole synthesis with a cis-configurated octahydroisobenzofuran-6-one yielded exclusively a furo[3,4-c]carbazole derivative as the product of a regioselective angular annulation reaction. A Friedländer quinoline synthesis from the same substrate gave a mixture of angular and linear annulation products, i. e. furo[3,4-a]acridine and furo[3,4-b]acridine derivatives. When submitting a mi...

Novel routes for the preparation of 2-amino-4H-pyran-3-carbonitrile 9, amino-arylbenzoic acid ester derivatives 13a,b, 2-aminotetrahydro-4H-chromene-3-carbonitrile 18, 3-amino-4-cyanotetrahydronaphthalene-2-carboxylic acid ester 26 and 4-amino-3,5-dicyanophthalic acid ester derivatives 37a-c were developed. The synthetic methods utilize one-pot reactions of acetylene carboxylic acid esters, α,β...
