Uses
Different sources of media describe the Uses of 994-89-8 differently. You can refer to the following data:
1. Used to prepare vinylstannanes and stannylisoxazoles. Ethynylation reagent for azaaromatics.
2. Ethynyltributylstannane can be used as a reactant to prepare: Terminal arylacetylene derivatives by Stille coupling reaction with aryl halides in the presence of palladium catalyst. 1,4-bis(tributylstannyl)but-1-en-3-yne by dimerization using a metal complex having bulky ligand catalyst system. Isoquinolone derivatives by reacting with benzotriazinones via denitrogenative insertion in the presence of nickel catalyst. Enyne key intermediates in the total synthesis of (-)-acutumine and (-)-dechloroacutumine.
Purification Methods
Purify it by dissolving the reagent (ca 50g) in heptane (250mL), washing it with H2O (100mL), drying (MgSO4), evaporating and distilling in a vacuum. It has IR: max 3280 ( C), 2950, 2850, 2005 (CC), 1455, 1065 and 865cm-1. [Bottaro et al. J Org Chem 46 5221 1981, Stille & Simpson J Am Chem Soc 109 2138 1987, Zavgorodnii et al.

Check Digit Verification of cas no
The CAS Registry Mumber 994-89-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,9 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 994-89:
(5*9)+(4*9)+(3*4)+(2*8)+(1*9)=118
118 % 10 = 8
So 994-89-8 is a valid CAS Registry Number.
