... and 50 mM of Bu4NBr were used. The reactions were performed under an argon atmosphere because it is known that the complex is hydrolysed when both water and air are present [22]. The progress of the reaction was monitored by GC. The addition of acid (HCl) was necessary for the reaction to proceed (v ...
