Notes:
13C NMR chemical shifts and 13C-31P coupling constants of fourteen derivatives from 3,9-di(alkylphenoxy)-2,4,8,10-tetraoxa-3,9-diphosphaspiro[5.5]undecane and of eight derivatives of the 3,9-dioxo type are reported. All investigated compounds possess a chair conformation with the lone pair or the phosphoryl oxygen in the equatorial position. The alkylphenoxy groups are in a cis position with respect to the lone pair or the phosphoryl oxygen. Conformational changes about the aryl—O bond can be monitored via 31P—O—C—13C couplings and their angular dependence was found to be non-symmetric.
