Edexcel Chem Organic Synthesis Maps

does anyone have any good organic synthesis maps for edexcel A level chem? I have a couple but they’re either not detailed enough for my liking or too messy, can’t get the right balance.

I found this map on Page 17 of this https://chemrevise.org/wp-content/uploads/2021/02/18.-organic-chemistry-iii-edexcel.pdf
not sure how im gonna go about memorising all this 😭

I like this one. It has blank ones so you can try and memorise them.

That's OCR's organic synthesis pathway. Whilst it has most of the stuff you need for the Edexcel course, there are a few differences:

-It does not include LiAlH4 being capable of reducing carboxylic acids, ketones and aldehydes to alcohols.

-It does not include LiAlH4 being capable of reducing amides to amines.

-Edexcel prefers conc. HCl as the reagent for converting an alcohol to a chloroalkane and red phosphorus / iodine for the conversion of an alcohol to an iodoalkane. OCR and Edexcel do agree that 50% H2SO4 and NaBr are the appropriate reagents to form a bromoalkane, though.

-Edexcel also expects you to learn about Grignard reagents. I can give you a quick 101 on them if you aren't aware of them.

-Edexcel prefers PCl5 as the chlorinating agent when converting carboxylic acids to acyl chlorides, whereas OCR prefers SOCl2.

-The Friedel-Crafts alkylation of benzene (e.g haloalkane + AlCl3 or alkene + HCl + AlCl3) is not required by Edexcel

-The reaction of phenol with dilute HNO3 is not required by Edexcel
