Abstract

Abstract: yield by Grignard cyclization of diethyl 5-bromo-3-bromoethylpentylphosphonate (13) in refluxing tetrahydrofuran. In an analogous fashion, 1-phosphabicyclo [2, 2, 2] octane 1-oxide (2) was prepared in 6 yield. The sublimable solids were characterized by elemental analyses, mass spectral fragmentation patterns, and by both proton and carbon-1 3 nmr spectroscopy. The proton nmr spectra at 60 MHz of both 1 and 2 were resolved using the ...
