| Abstract: | A New Synthesis for Nitrosyl Salts with Weakly Coordinating Anions Exemplified by NO[B(CF3)4] A new synthesis for nitrosyl salts of weakly coordinating anions is described, using the corresponding guanidinium salts as starting materials. The guanidinium salt [C(NH2)3][B(CF3)4] was obtained by a metathesis reaction of K[B(CF3)4] with [C(NH2)3]Cl. Treatment of the guanidinium salt with liquid NO2 resulted in analytical pure NO[B(CF3)4] in quantitative yield. The guanidinium and nitrosyl tetrakis(trifluormethyl)borates were characterized by vibrational and NMR spectroscopy as well as by DSC measurements. |
