Intercalation reaction with Vanadium
« on: October 19, 2017, 07:58:41 AM »
I'm studying 2 intercalation reactions of V2O5. In the first one V2O5 was mixed with hexane and nbutyl lithium and a colour change of orange to dark green was seen. For this reaction i think the equation is

V2O5 + xBuLi -> LixV2O5 + x/2C8H18. (please do say if thats incorrect)

I also think the structure of vanadium pentoxide is a layered structure so 2D intercalation would occur.
The next reaction is to mix V2O5 + LiI.H2O in dichloromethane. The colour change is the same for the solid (orange to dark green) and the solvent goes from colourless to pink. From this i figure that the same complex as above must be made as the colour is the same. However i am a little confused as to how the reactions differ and if someone could explain the difference in the reactions that would be very much appreciated.

The pink colour in DCM suggests the formation of I2, which suggests a reaction analogous to that with BuLi.
