Several alkyl-, aryl-, and perfluoroalkylcyclopolyphosphines have been examined by NMR,
ir-Raman, and mass spectroscopy. It is found that three-, four-, and five-membered rings can …

The 31P|* H¡ or j19F¡ NMR spectral analysis of five cyclotetraphosphanes (RP) a (R= CH3, Z-

The reaction of trifluoromethyl dichlorophosphine (CF3PCl2) with mild reducing agents
results in the formation of CF3-substituted cyclooligophosphines (CF3P) n (n= 3–5). The …

Although the commercial manufacture of the element phosphorus did not develop until the
1830's and by 1844 the total phos [ahorus production in Great Britain was estimated at only …

Introduction First of all, I offer sincere thanks to the many graduate students and postdoctoral
associates it has been my privilege and pleasure to work with over the years, two of whom …

Since Heyrovsky made the first polarographic measurements in 1921, electrochemical
techniques have grown to become invaluable to analytical chemists. Even more recently …

The first crystal and molecular structures of hydrated bis (n-perfluoroalkyl) phosphinic
acids,[H3O]+[(Rf) 2PO2]−(Rf= C6F13, C7F15 or C8F17), have been determined by single …

Cyclopolyphosphines are a class of organophosphorus compounds which contain only
phosphorus in the ring and have the general formula (RP),-Although a number of such …
