Resolution of lj-cyclononadiene. Cope et al. examined the resolution of the cyclic allene 1,2-cyclononadiene (1) by way of the diastereomeric platinum complex containing this amine (compare resolution of cycloalkenes (2, 272-273)). A... 

Cyclic organic compounds alicychc cycloalkanes and cycloalkenes and aromatic hydrocarbons constitute a group of gases which are very toxic. Cycloalkenes (e.g. limonene, a—pinene) predominate the concentration of cycloalkanes (e.g. cyclobutane, cyclohexane). The concentration of the cycloalkanes in the gas formed in landfills in the United Kingdom ranged from 80 to 487 mg m (Allen et al. 1997).
