Three cyanate esters containing phosphorus are synthesized in good overall yields starting from bromoanisoles. Di- and tricyanates with meta configuration are most stable while para is less so. The para dicyanate ester isomer is particularly affected by water from the atmosphere. The meta dicyanate ester 2 has good thermal properties with glass transition at 268 °C and char yield of 65% in air at 600 °C. All three phosphorus-containing cyanate esters are low flammability in an open flame. They make highly combustible cyanate esters resins less flammable simply by blending. Mixing 10 wt% dicyanate ester 2 into bisphenol A or E dicyanate esters makes them rate V-0. Published 2018.? J. Polym. Sci., Part A: Polym. Chem. 2018, 56, 1100–1110.
Synthesis of a family of triarylphosphanes with fluorous phase affinity

A very efficient synthesis of new perfluoro-functionalized triarylphosphanes using an oxygen substituent as the branching point for the introduction of the perfluoro chain has been developed. This approach enabled the introduction of the perfluoro tail at the para, meta, and oitho position, giving highly perfluorinated analogues of triphenylphosphane con-taining between 54 and 59 wt% fluorine. This methodology has been extended to the synthesis of a perfluoro analogue of l,2-bis(diphenylphosphanyl)ethane. Fluorous/organic partition coefficients of some of the perfluorophosphanes have been measured, as well as their rates of oxidation. WILEY-VCH Verlag GmbH, 2002.
