This reaction is crucial for the synthesis of various fullerene derivatives with potential applications in materials science, pharmaceuticals, and nanotechnology.
Purification Methods
Purify it by recrystallisation in the presence of Me2S. A solution of the complex (1.02g) in Me2S (5mL) is slowly diluted with hexane (20mL), and the pure colourless prisms of the complex (0.96g) separate and are collected and dried, m 124-129o(dec). The complex is insoluble in hexane, Et2O, Me2CO, CHCl3 and CCl4. It dissolves in DMF and DMSO, but the solution becomes hot and green indicating decomposition. It dissolves in *C6H6, Et2O, MeOH and CHCl3 if excess of Me2S is added and a colourless solution is obtained. [House et al. J Org Chem 40 1460 1975.] Prior to use, the complex is dissolved in Me2S and evaporated to dryness in the weighed reaction flask [Bourgain-Commer.on et al. J Organomet Chem 228 321 1983].
Check Digit Verification of cas no
The CAS Registry Mumber 54678-23-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,6,7 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 54678-23:
(7*5)+(6*4)+(5*6)+(4*7)+(3*8)+(2*2)+(1*3)=148
148 % 10 = 8
So 54678-23-8 is a valid CAS Registry Number.
