The titanocene complex 1b reacts with triethyl and trimethyl phosphite to yield the phosphonoesters 3a,b, which exist in solution as a mixture of two interconvertable conformers. The titanocene complex la is alkylated by trimethyloxonium tetrafluoroborate to form the 1,3-dithiolium tetrafluoroborate 10. The latter interacts with 9 (the lithium salt of 3a) merely by proton transfer restoring 3a. 9 condenses
