| | TRIBUTYLSTANNYLTRIMETHYLSILANE Usage And Synthesis |
| Physical properties | colorless liquid. bp 88 °C (0.2 mmHg). | | Uses | Trimethylsilyltributylstannane is used for the vicinal bis-functionalization of alkynes, dienes,
allenes, activated olefins, 1,1-addition to isonitriles, for generation
of metal-free aryl and vinyl anions, for generation of benzynes and
quinonedimethanes; stereoselective bis-functionalization-cyclization of diynes, eneynes, bis-allenes, alleneynes, and allenealdehydes; silylation of allylic, propargylic derivatives, and aryl
bromides; formation of silyl and stannyl cuprates.It takes part in the reactions of Addition to Alkynes, Synthetic Applications of β-Trialkylsilylvinylstannanes, Addition to Isonitriles, Addition to Alkenes and 1,3-Dienes, Addition to Activated Double Bonds, Addition to Allenes, etc. | | Preparation | By treating freshly distilled tri-n-butylstannane with LDA followed by quenching with chlorotrimethylsilane. |
