{ALF} The reagent formed with DMSO at low temperatures provides an alternative to the Swern oxidation for selective conversion of alcohols to carbonyl compounds: Tetrahedron Lett., 43, 8355 (2002).

{ALF}

{ALF} Reagent for the conversion of alcohols and phenols to bromides in good yields: J. Org. Chem., 37, 626 (1972). Particularly useful for alcohols where sensitive functionality is present: J. Org. Chem., 49, 431 (1984); Synth. Commun., 22, 2945 (1992). Cleaves dialkyl ethers to the two alkyl bromides: J. Am. Chem. Soc., 86, 5037 (1964); J. Org. Chem., 37, 626 (1972).

{SA} 2. Synth. Commun. 22 , 2945, (1992)

{ALF} Ureas are dehydrated to carbodiimides: Liebigs Ann. Chem., 718, 24 (1968); Synthesis, 373 (1981).

{ALF} Reaction with amines gives iminophosphoranes, which have been used as a means of blocking an amino group to permit monoalkylation: Synthesis, 295 (1980). Iminophosphoranes also undergo a Wittig-like condensation with CO2 or CS2 to give the isocyanates or isothiocyanates respectively: Synthesis, 596 (1982):
