Abstract
RECENTLY1 we reported that treatment of tris(triphenylphosphine)chloro copper (I) with hydrazine in alkaline alcoholic solution yielded a compound of empirical formula Cu(PPh3)2. Analytical data (Table 1) were consistent with this formulation, the standard method for the detection of chlorine having proved negative. Further study has shown that some chlorine is indeed present and furthermore, by chance, analysis for C, H and P does not distinguish this compound from the starting material [Cu(PPh3)3Cl]0.
