The crystal structures of the title compounds, 1,3-di-tert-butyl-2,3-dihydro-1H-1,3,2-diazasilol-2-ylidene, C10H20N2Si (1) and 1,3-di-tert-butyl-2,2-dichloro-1,3-diaza-2-sila-4-cyclopentene, C10H20N2SiCl2 (3) were solved and are reported. Compound (1) crystallized in space group P mmn and each molecule has a mirror plane, which bisects the C-C backbone of the N-C-C-N framework. Compound (1) was...

Some recent publications have revealed the presence of phthalates in rather unexpected locations (1-4). Mayer (3) reported that di-n-butyl phthalate and di-2-ethylhexyl phthalate had measurable effects on the Daphnia, an accepted subject for studying the aquatic food chain in the environment. The ubiquity of phthalates has been well documented. Their presence in stored blood samples and in some...

We synthesized two hexaazaphenalene derivatives, 6AP-Pm (2,5-di(tert-butyl)-1,3,4,6,7,9b-hexaazaphenalene) and 6AP-Pz (2,5-di(tert-butyl)-1,3,4,6,8,9b-hexaazaphenalene) compared the electronic properties with pentaazaphenalene derivative 5AP (2,5-di(tert-butyl)-1,3,4,6,9b-pentaazaphenalene). clarified position-dependent effects of aza-substitution on states followed by optical electrochemical p...

The phenyl and tert-butyl groups of the title compound, C27H25NO3, exhibit a trans configuration in agreement with the stereochemistry of the Z phenyl-N-tert-butyl-nitrone starting material. The attached carbonyl groups are not coplanar with the neighboring di-hydro-isoxazole ring and the phenyl rings they are bonded to, with torsion angles of 59.26 (8), 17.53 (11), 16.52 (12) and 52.86 (7)°. T...

Di-Tert-Butyl-Peroxide Di-tert-butyl peroxide (DTBOO) a sufficiently stable molecule is a good candidate as precursor for the production and investigation of C4 – OO peroxy radicals. The most prominent absorption ( *-*) in DTBOO is in the UV spectral range between 340 nm and 230 nm. In order to learn more about the state manifolds connecting to the states of the fragments we started single phot...
