An Improved Protocol for the Aldehyde Olefination Reaction Using (bmim) (NTf_𝟐) as Reaction Medium

Table 3

Recyclability test for p-anisaldehyde olefination reaction.

Recyclability run	Isolated yield (%)^a	(𝐸/𝑍)^b
1	85	10 : 1
2	80	8 : 1
3	78	7.5 : 1
4	71	6.5 : 1
5	72	6.5 : 1

^aYield was calculated after column chromatography.
^bAll 𝐸/𝑍 ratios were calculated by ¹HNMR.
