- A new in situ preparation of trimethylsilyl trifluoromethanesulfonate (3) is described: 3 is generated by a thermally induced rearrangement of (dimethylsilyl)methyl trifluoromethanesulfonate (2), which can be prepared by reaction of (CH\(_3\))\(_2\)Si(H)CH\(_2\)OH (1) with (CF\(_3\)SO\(_2\))\(_2\)O. Starting with C\(_6\)H\(_5\)(CH\(_3\))Si(H)CH\(_2\)OH (5), the derivative (methylphenylsilyl)methyl trifluoromethanesulfonate (6) can be obtained by a similar method. Its thermally induced rearrangement Ieads to dimethylphenylsilylA new in situ preparation of trimethylsilyl trifluoromethanesulfonate (3) is described: 3 is generated by a thermally induced rearrangement of (dimethylsilyl)methyl trifluoromethanesulfonate (2), which can be prepared by reaction of (CH\(_3\))\(_2\)Si(H)CH\(_2\)OH (1) with (CF\(_3\)SO\(_2\))\(_2\)O.

Its thermally induced rearrangement Ieads to dimethylphenylsilyl trifluoromethanesulfonate (7). The rearrangements 2---> 3 and 6---> 7 were found to be first-order reactions with half-lifes at 80 oc of 0.75 and 1.7 h, respectively.…
