Treatment of a CuSO4 . 5H(2)O solution with NH2OH . HCl and NaOH produces o
range-yellow Cu2O, which on being reacted with Ph3P and aqueous HF (48%) in
MeOH or EtOH yields CuF(PPh3)(3) . 2ROH (R = Me or Et) in high yield. The
volatile compounds have been characterised by spectroscopic techniques in a
ddition to chemical analyses and solution electrical conductance measuremen
ts. Typically, CuF(PPh3)(3) . 2MeOH appears to be stable up to 118 degrees
C and loses 2 MeOH and 3 PPh3 between 118 and 274 degrees C yielding volati
le 'CuF' at 274 degrees C.
