Is it possible to lower the IPA or use other methods to lower the capacity
Yes, but the mechanisms of reactions are slightly different.You can also do a selective bromination using copper (II) bromide
No. There will be problems with purity and yield.

Preparation 2-iodo-4-methylpropiophenone The so-called iodoketone Place in a beaker 4-methylpropiophenone 150ml (148.90g) N-iodosucinimide 270g P-Toulenesulfonic acid monohydrate 228g We cover the glasses with a glass lid not tightly. We put it in the microwave and set it to 700w. We illuminate 3 times for 1 minute with 30-second breaks between sessions. We are waiting for the romance to cool down to temperature. Pour 300 ml of internal water with ice into the water and mix thoroughly. An iodoketone will arise almost immediately We filter on the filter and 2 or 3 more times We wash the water Crystallization 1g of iodoketone add 0.5ml or 0.7ml dcm mixed in a canister and put into the freezer -20 overnight After a night, filter it and then dry it. Yield 210g to 215g of pure iodoketone will me ok ??
