TRIBUTYLPROPYNYLSTANNANE Chemical Properties,Usage,Production

Chemical Properties

clear colourless liquid

Uses

Tributyl(1-propynyl)tin can be used:

• As a starting material in the synthesis of phenyl-substituted pyrimidine-dione by reacting with ethyl isocyanate via cycloaddition and Stille coupling reactions.
• In the synthesis of ¹⁸F labeled triazolo quinoline derivative, a positron emission tomography (PET) ligand used in the in vivo imaging of metabotropic glutamate receptor type 1.
• In one of the key synthetic steps for the synthesis of 4-(1-aryltriazol-4-yl)-tetrahydropyridines as potent mGluR1 antagonists.
