Mild thermolysis (at 110–150 °C) of 1,3,2,4-benzodithiadiazine 1 and its derivatives 2–6 in hydrocarbon solvents quantitatively yielded stable 1,2,3-benzodithiazolyl π-radicals via a first-order reaction ( E a = 76.2 kJ mol –1 , k 0 = 4.34×10 5 s–1 for 1).
The first example of the ring transformation of 1,2,3-thiadiazoles involving four atoms of the side chain to form 5 H -(1,2,3)triazolo- (5,1- b )(1,3,4)thiadiazines is presented.
The formation of phthalonitrile from 1-Cl-4-X-phthalazines possessing a substituent capable of anionic elimination in the 4-position (X = Cl, OPh or OMe) was found to be induced by electron transfer.
A new rapid method for the calculation of sorption isotherms from the dependence of retention volumes on concentrations with the use of an equation in the form of virial expansion was suggested.
A new approach to the synthesis of monophosphorylated glycols with the use of P III -benzimidazolide has been suggested
The red photoluminescence (λ max = 580±20 nm) observed in the synthesis of the Ph 3 C Gomberg radical is assigned to a luminescence of the (Ph 3 C–Ph–ĊPh 2 )* radical dimer.
The addition of amidoximes to acetylene in the presence of the KOH–DMSO superbase system afforded O -vinylamidoximes in 26–59% yields.
The treatment of substituted ethyl 1-(3’,4’-dihydro-3’,3’-dimethylisoquinolyl)-1-oximinoacetates with hydrazine hydrate leads to a 3,4-dihydroisoquinoline ring enlargement with the annulation of a pyrazole ring to form substituted 5,5-dimethyl-2,3,5,6-tetrahydro- 3-oxopyrazolo(3,4- b...
Aromatic tert -alkylamines and N -(5-oxo-2,5-dihydro-1 H -pyrrol-2-yl)acetamides were successfully prepared using the Ritter reaction under mild dilute conditions.
The synthetic approaches to novel N- and SO 2 -containing bi-, tri- and tetracyclic systems, 6,8-di- and 2,4,6,8-tetraalkyl-7-oxo-3- thia-2,4,6,8-tetraazabicyclo(3.3.0)octane-3,3-dioxides, 8,12-dioxo-9,11-dimethyl-4-thia-1,3,5,7,9,11-hexaazatricyclo(18.104.22.168 10,13 )- tridecane-4,4-dioxide and...
