摘要：

Reduction of 3,5,7,7,10,12,14,14-octamethyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene (Me8[14]diene) with sodium borohydride yields three isomeric Me8[14]anes (L(A), L(B), and L(C)). These macrocycles give green trans-[CoLCl2]ClO4 diastereoisomers. It has been possible to obtain two diastereoisomers each with L(A) and L(B) and one diastereoisomer with L(C). These isomers give distinct infrared and H-1 NMR spectra. The structures of these isomers have been assigned on the basis of their H-1 NMR spectra. The structure of one isomer, trans-[CoL(A-alpha-Cl2]ClO4, has been confirmed by X-ray crystallography.
