A convenient one‐pot method for the synthesis of various substituted succinimides has been developed. By starting from commercially available amines (or ammonia) and alkynes, a range of interesting succinimides have been obtained selectively in the presence of either [Fe(CO)5] or [Fe3(CO)12] (see scheme; R′=H, alkyl, aryl; R′′, R′′′=alkyl, aryl).

Various boronicacids were treated with a rhodium (I) catalyst enabling their 1,4-conjugate addition to unprotected maleimide. The scope of the reaction was explored to include both electron-rich and electron poor boronicacids. These reactions were also performed in the microwave resulting in reduced reaction times and improved efficiencies. Additionally, substrates that were recalcitrant under conventional
