Phosphoryl fluoride reacts with dimethylamine in an equimolar ratio to yield volatile dimethylaminophosphoryldifluoride. The residual solid is a mixture of dimethylammonium hexafluorophosphate and dimethylammonium difluorophosphate salts rather than the simple fluoride salt. Dimethylamine reacts slowly with dimethylaminophosphoryldifluoride to yield bis(dimethylamino)phosphorylfluoride and the same complex fluorophosphate anions in the solid products. Physical data are reported on the alkylamino phosphoryl fluorides. The reaction of the difluorophosphoryl compound with hydrogen halides has been studied.

Mucolytic Agent

A general synthesis for 1,3-diphenylurea and 1,3-diphenylthiourea derivatives of mucolytic agent bromhexine is described by reactions of different commercially available phenyl isocyanates and phenyl-isothiocyanates at room temperature without any additional catalyst and additive. Using commercially available electron donating and electron withdrawing phenyl isocyanates in the transformation of bromhexine into urea derivatives proceeded from moderate to high product yield (42-90%). Bromhexine resulting compounds add a general interest in the fields of Pharmaceuticals, diagnostics and materials.
