Use of SiO2
« on: April 13, 2024, 03:57:29 PM »
Hello all,

I am studying the homoallyl radical rearrangement and I just ran into these reaction conditions (see image). I don't get why they used SiO2? Do you have any idea ?

Thanks in advance for your help.

Best,
Liz

It seems like a ring closure under mild acidic conditions, but you need the full paper to really know this. SiO2 is a little acidic and also contains some water. The b-conditions are divided into 2 parts so its 2 steps really as far as I understand
