Question on mCPBA / RCO3H

[Mycoalwin]

Somewhat confused on mCPBA and R-CO3H as reaction conditions. Since these are both roughly the same in structure, how do I know when the R-CO3H will:

1) do the same as mCPBA (make epoxide)
2) add two -OH's Anti across a double bond (found in Chad's notes)
3) perform the Bayer-Villiger reaction (making ethers; found in 2012 Destroyer)

Based on bootcamp, it seems like I'll never have to worry about this, but just wanted to make sure...

mCPBA and R-CO3H will always add epoxide; they're both the same things as you said so yourself.

when it does double OH it's when something else attacks from the side. there needs to be another reagent to make it have 2 OH's or other stuff. like 1)MCPBA 2) EtOH/H2SO4 or something.

Don't worry about bayer-villiger you will never see that complicated stuff on DAT. Focus on Chad's/BC/qvault (if you have money)

Ah, misread the reaction conditions for the anti-diol product in Chad's notes. Thanks a bunch, @emminent
