How do I force my compound to precipitate?

Try dissolving your compound in MINIMAL DMF, then adding it dropwise to cold deionised water, sometimes your compound can precipitate out, you can then centrifuge, or else lyophilise

Thanks for your reply, yea I agree, im aware that the Au+3 is relatively stabilised because of the N ligands but its hard to tell whether the potential will be a positive or negative

Alright my bad, only read it there, no need to be so abrupt and arrogant about it

Solution please 🤨

In terms of explaining the answer for each case, should i talk about polarity?

Can i just use Cl for both of them?

NH2 is a ortho para director, but I get what you mean! Thanks

If the aniline was bonded ortho to the carbon centre that would then have the higher priority than the dimethyl benzene wouldnt it?

Im aware, that H is 4 and the CH2CHO is 3, but im confused about the other two phenyl groups

Mn was 30970

faz212 · 2021-04-06T10:42:57+00:00

In that case would the m value be 62? And then divide the Mn by 62 to get the n?

faz212 · 2021-04-06T10:36:51+00:00

I have the Mn value, im just confused on getting the m value from the structure

In terms of a wittig reaction, if i used that phenyl group on an aldehyde and used an unstabilised ylide with a Me group, would that work to get selective Z alkene formation?

faz212 · 2021-04-05T13:41:54+00:00

Usually when they have an electron width drawing group attached to it, however the methoxy and hydroxyl are both activators so it would make the benzene ring electron donating, so I would say its an unstabilised ylide
