12078-25-0 Usage

Reactions

Volatile cobalt complex used for the deposition of cobalt and cobalt oxide films. Intramolecular cobalt-catalyzed [2+2+2] cycloaddition of O-protected diyne-cycanohydrins. Catalyst used for the dehydrative direct CH allylation with allylic alcohols.

Chemical Properties

dark red to brown liquid

Uses

Different sources of media describe the Uses of 12078-25-0 differently. You can refer to the following data:
1. Dicarbonylcyclopentadienylcobalt Catalyst for the cyclotrimerization of alkynes. It mediates the [2+2+2]-cyclization of allenediynes to tricyclic systems. catalyzes the formation of pyridines from a mixture of alkynes and nitriles.
2. Mediates the [2+2+2]-cyclization of allenediynes to tricyclic systems.

Purification Methods

Best distilled in an atmosphere of CO in a vacuum. The red brown liquid decomposes slightly on distillation even in a vacuum to liberate some CO. Operations should be performed in an efficient fume cupboard. It is soluble in organic solvents and stable in air but decomposes slowly in sunlight and rapidly under UV. [Piper et al. J Inorg Nucl Chem 1 165 1955, Beilstein 16 IV 1827.] TOXIC.

Check Digit Verification of cas no

The CAS Registry Mumber 12078-25-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,7 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 12078-25:
(7*1)+(6*2)+(5*0)+(4*7)+(3*8)+(2*2)+(1*5)=80
80 % 10 = 0
So 12078-25-0 is a valid CAS Registry Number.
