Propin-2yl-aminyloxide 225 decomposes only when refluxed in benzene solution giving bicyclic compound 226, the structure of which was confirmed by X-ray analysis184. Apparently the first step of this reaction is again the a-scission of a N-C-bond giving l.l-dimethyl-2-propinyl radical and 2-methyl-2-nitrosopropane, compound 226 being formed in an as yet unknown sequence of reactions. 

Two methods are used for the preparation of capillary gas adsorption columns the suspension method, in which the inner walls of the column are coated with a suspension of the adsorbent, and the chemical method, in which an adsorption layer is formed on the walls of the column through a process of synthesis of the adsorbent in the capillary column. Recently, a new type of porous polymer (poly(l-(trimethylsilyl)-l-propin) (PTMSP)) has been suggested as an organic adsorbent and has been actively studied as a promising material in membrane technology. This polymer dissolves well in some volatile solvents, and a layer of it can be formed in a capillary column using simple techniques for coating from a solution of a stationary phase in a volatile solvent.
