“…Although this fact indicates that the crystal is either the cis, cis-tetrachloro-or the trans, transtetrachloro form, it is difficult to say which is the case. Miura & Haga inferred that it may be the cis, cis form, in view of the fact that the 1,2,3,4-tetrachlorobutadiene from hydrolysis ofhexachlorotellurophene has a melting point of 51°C (Mack, 1965). The present author attempted an X-ray structural analysis of the crystalline 1,2,3,4-tetrachlorobutadiene, in order to confirm their conclusion.…”

“…Arbusov and Kataev [88,89] have used methylated analogues starting from conjugated dienes and elemental selenium at 380-420°C. Tetrachloroselenophene is formed by the reaction of selenium with an equimolar quantity of hexachlorobutadiene at 250°C [90]. Okuma has demonstrated that the reaction of tetracyanoethylene 44 (TCNE) with the seleno derivative 43, affords an unexpected selenophene 45 in refluxing toluene (Scheme 17) [92].…”

tuted 2-oxazolines (3) and products of their reaction with the excess of epoxide. We assume that the 1 : 1 addition products (2) are first formed and that these are then converted into the 2,5-disubstituted 2-oxazolines (3) by loss of ethylene sulfide (thiirane) (or its polymers). Depending on the reaction time and the amount of epoxide these products (3) may react further to give 4,6-dioxa-l-azabicyclo[3.3.0]octanes (4).
