Syntheses, stereochemistry, and inclusion properties of new spirocyclophosphazenes
Abstract
The syntheses and characterization of new spirocyclophosphazenes is reported. Variable-temperature n.m.r. measurements strongly suggest the presence of only one isomer for our compounds. Only tris-(3-methoxyphenyl-1,2-dioxy)phosphonitrile trimer has been found to form clathrate compounds with cyclohexene, n-heptane, and 1,2-dichloroethane.
