64424-68-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 64424-68-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,4,2 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 64424-68:
126 % 10 = 6
So 64424-68-6 is a valid CAS Registry Number.

Reaction of Fe(CO)2(η2-CS2){P(OR)3} 2 with phosphines: Desulphurization versus substitution. Crystal structures of Fe(CO)2(CS){P(OPh)3}2 and Fe(CO)3{P(OPh)3}2


, p. 201 - 207 (2007/10/03)

The reaction of Fe(CO)2(η2-CS2){P(OPh)3} 2 1 with two equivalents of PBu3 in a minimum volume of a polar solvent such as acetonitrile or dimethylsulfoxide afforded the thiocarbonyl derivative Fe(CO)2(CS){P(OPh)3}} 2 in ca. 80% yield whereas reaction in solvents such as dichloromethane or benzene afforded the substitution products Fe(CO)2(η2-CS2){P(OPh) 3}(PBu3) and Fe(CO)2(η2-CS2)(PBu3) 2. Although desulphurization of Fe(CO)2(η2-CS2){P(OR)3} 2 by PBu3 in polar solvents is not a general route to Fe(CO)2(CS){P(OR)3}2 for all R, the new compound Fe(CO)2(CS){P(OEt)3}2 has been obtained and characterised spectroscopically. The crystal structures of 2 and Fe(CO)3{P(OPh)3}2 were determined and are very similar. Both compounds are trigonal bipyramidal about the Fe atom with trans apical phosphite ligands and a trigonal planar arrangement of CO/CS groups. The CS ligand in 2 was found to be disordered over two sites with occupancies 0.63 and 0.37.
