NiCl2·2H2O + 2 PPh3 + 2 HC(OC2H5)3 → [NiCl2(PPh3)2] + 2 HC(O)OC2H5 + 4 C2H5OH

and

NiCl2·2H2O + dppe + 2 HC(OC2H5)3 → [NiCl2(dppe)] + 2 HC(O)OC2H5 + 4 C2H5OH

where Ph = C6H5 and dppe = Ph2PCH2CH2PPh2.

If 0.186 g of NiCl2:2H20 reacts with 0.577 g of PPhz in the presence of a slight excess of triethyl orthoformate, how many grMW of  [NiCl2(PPh3)2]= 654.2 g/mol

MW of NiCl2·2H2O= 165.6 g/mol

MW of PPh3= 262.3 g/mol

Mw of Triethyl orthoformate HC(OC2H5)3 = 148.2 g/mol

density of triethyl orthoformate HC(OC2H5)3 = 0.891 g/ mL
