| | (IODOMETHYL)TRIMETHYLSILANE Usage And Synthesis |
| Chemical Properties | CLEAR YELLOW TO BROWN LIQUID | | Physical properties | bp 140–142 °C; d 1.442 g cm3. | | Uses | (Iodomethyl)trimethylsilane can be used as electrophile for the preparation of allylsilanes and propargylsilanes;
forms carbon alkylation adducts useful for alkene
synthesis; alkylation adducts are frequently a source of fluorideinduced
reactive intermediates, forming nitrogen and sulfur
alkylation adducts that function as ylide precursors; readily undergoes
metal–halogen exchange to generate a reagent for Peterson
methylenation. | | Uses | (Iodomethyl)trimethylsilane is used for the N-alkylation of amides, in a reaction sequence to prepare unstabilized ylides for [2+3]-cycloadditions. It can react with acetoacetic acid ethyl ester to get 3-trimethylsilanyl-proπonic acid ethyl ester. | | Purification Methods | If slightly violet in colour, wash it with aqueous 1% sodium metabisulfite, H2O, dry (Na2SO4) it and fractionally distil it at 760mm.
