    Was wondering how you would know how to constuct one for an SN2 reaction that has phase transfer catalysis going on...

    Thanks guys

    Well drawing a reaction coordinate diagram for an SN2 is pretty straight forward. I'm just trying to think how having two phases has a bearing on it.

    Okay, I'm going to say its not that different with a phase transfer catalyst. Taking an example: RBr + CN- ---> RCN + Br- using TBAB (tertbutyl-ammonium bromide) as a phase transfer catalyst.

    Instead of free CN- attacking we have TBA+CN- (after undergoing anion exchange in the aqueous phase between NaCN and TBAB). So we need to draw its formation on the reaction coordinate diagram. Then we have the 'normal' Sn2 reaction occuring in the organic phase reforming the TBAB (then does another anion exchange, the cycle continues)
