The title compounds, C15H14N2OS (1a), C16H16N2OS (1b), and C17H18N2OS (1c), form a homologous series in which the size of the saturated ring increases from six- to eight-membered (with four, five and six methylene groups respectively). For 1b and 1c,
The molecule of the title compound, C17H11NO2S, is almost planar, with an interplanar angle of 3.01 (3)° between the benzothiazole and chromene ring systems. A short intramolecular S...O=C contact of 2.727 (2) Å is observed. The crystal packing inv

In this O-alkylated sulfonylpyrazolone, the sulfur atom lies 0.558 (1) Å out of the pyrazole ring plane. The NH2 group is involved in an intramolecular hydrogen bond to a sulfonyl oxygen atom and in a three-centre system with the two oxygen at

A phosphine-catalyzed oligomerization of arynes using selenocyanates was developed. The use of JohnPhos as a bulky phosphine is the key to accessing α,ω-bisfunctionalized oligo(ortho-arylenes) with RSe as the substituent at one terminus and CN as t

A novel class of highly activated donor-acceptor cyclopropanes bearing only a single, vinylogous acceptor is presented. These strained moieties readily undergo cycloadditions with aldehydes, ketones, thioketones, nitriles, naphth-2-ols and various ot
