Eleven Atoms

This aldehyde, which has the formula CuHjgO, appears to be the only aldehyde with eleven atoms of carbon yet found in essential oils. It was isolated from santal oil by Schimmel Co., who gave the follow-...

Probably, the dramatic distinction in stereo-selectivity between cometathesis products obtained from Z-cyclodecene and from cycloolefins C5-C9 (Table 3), is connected with the fact that Z-cyclodecene gives the cyclic transition state having eleven atoms in the cycle (10 C-atoms + 1 Mo-atom). Meanwhile, it is known that the thermodynamic stability of E-isomers in the range of unsaturated cycles of different size dramatically increases beginning from cycloundecene [33]. So, Z-cycloolefins C5, and C7-C9 in cometathesis reaction with a-olefins allow predominantly Z-isomer new double bonds to be obtained (in l,A-dienes). This radically differentiates them from cycloolefins with number of C-atoms of 10 and more, as well as from open-chain olefins.

A mixture of auramine, acetyl auramine, and Michler s ketone, dissolved in alcohol, is a very difficult three-component problem because of the overlapping spectra (Fig. 2). If glacial acetic acid is used as solvent, the acetyl auramine is converted to an eleven-atom conjugated system and becomes an intense violet. The other two undergo little change and the mixture is readily amenable to quantitative analysis (Fig. 3).
