Question for a Photochromism Lab

Please provide an arrow pushing mechanism for each of the four synthetic steps: 1. Chalcone formation; 2. Dibromide synthesis; 3. Aziridine formation; 4. Imine formation.

If more information is needed let me know.

Answer 1

1) Chalcone formation mechanism - chalcone is an aromatic Ketone and an mone that forms the central core for variety of important biological compounds which are known collectively as chalcones or chalconoids Mechanism tho Acetophenone योजन Benzaldehyde hough a t the chalcone.

2) Dibromide formation mechanism It is an example of electrophilic g Bor to alkene. addition Mechanism. Step. L Attack on bromine to form bromonium son cyclohexene Bromonlum ion. I Bro Glep II - Attack on Bromonium jon to give dibromide + "By - Enantiomer. 3 Azindine formation mechanism. Azindine is the organic compound consisting 9 the three membered heterospode condaining nitrogen atong Mechani so addition

Page Nu Azinidine formation mechanizm - Base schiffsbase (Imine) An imine is a functional group or chemical compound containing carbon nitrogen double bond Nitrogen atom attached to hebogen to ang R group may be alleged or any or any other.
