Abstract Over 60 lignin-related model compounds were phosphitylated with 2-chloro-4, 4, 5, 5-tetramethyldioxaphospholane, a sterically hindered analogue of 2-chloro-1, 3, 2- dioxaphospholane used in earlier work, and their 31 P chemical shifts were recorded. Excellent resolution between the chemical shifts of phosphitylated carboxylic acids, phenols and aliphatic alcohols was obtained. The correlations of the phosphorus chemical shifts ...
