cf. CA 3311c. 7-(Dimethylamino)cycloheptatriene (I) was heated and isomerized to give II and finally III. In addn. were also isolated 5-8% C6H6 and a compd. C8H8(NMe2)2 (IV), b0.3 57 Deg. The following mechanism is offered: I -> C6H6 + CHNMe2; I + CH

Isomerization of the bicyclo[5.1.0]octadienyl anion

Autor: Kloosterziel, H., Zwanenburg, E.

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas, 88(12), 1373-1376. Royal Netherlands Chemical Society

NMR spectroscopy has revealed that the bicyclo[5.1.0]octadienyl anion (I) isomerizes by opening of the three-membered ring and a 1,2 shift of h to the 1,6-methanoheptatrienyl anion. The symmetry-forbidden electrocyclic ring opening of I to the cycloo

Photo-addition of trichloromethanesulfenyl chloride to carbon-carbon double bonds

Autor: Kloosterziel, H.

Publikováno v: Quarterly Reports on Sulfur Chemistry, 2(4), 353-355

The CL3CO radical in the photoaddn. of CL2CSCl to olefins isa chain-carrying radical. The structures of the adducts with styrene, propylene, allyl chloride, methallyl chloride, and allyl bromide are consistent with this conclusion, and the mechanism

Thermal isomerizations of trimethylcyclopentadienes

Autor: Haan, de, J.W., Kloosterziel, H.

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas, 84(12), 1594-1596. Royal Netherlands Chemical Society

The title reaction was studied in gas phase in a microreactor with residence times of 5-50 sec. and the products studied by their spectral data and their hydrogenation products. On heating 1,5,5-trimethylcyclopenta-1,3-diene at 350-400 Deg, it gave 1
