2-Furfurylidene-. (1a) and 2-thienylidene-1,3-indandione (1b) produce the respective 1:1 adducts (8 a-f) upon reaction with the appropriate dialkyl phosphite (3 a-c). The reaction of 1a,b with trialkyl phosphite (2a-c) yield a mixture of the corresponding phosphonates (7a-d) (major) and (8a-d) (minor). Triphenylphosphine (2d) and hexamethylphosphorustriamide (2e) also reacted with 1a,b. The produced betaines (10a-c) were alkylated with methyl iodide to yield the respective phosphonium iodides (11a-d). Possible reaction mechanisms were discussed. Compatible elemental and spectroscopic results were gained for the new products.
