A nickel schiff base complex was formed following the synthesis below: nickel(II) acetate tetrahydrate + pyrrole-2-aldehyde was reacted with a solution of ethanol/water and refluxed at 65oC. 2M sodium hydroxide was added along with a solution of 1,3-diaminopropane in water. The solid formed was dissolved in dichloromethane and heptane was added to it. The dichloromethane was evaporated off and the product was vacuum filtered. What is the reaction mechanism for this reaction and what is the name of the end product formed? Draw the structure of the product formed.
