levels of stereoselectivity by using cationic gold(I)‐phosphine complexes as catalysts. By choosing the appropriate phosphine, the selective formation of the Z or the E isomer of the vinyl ether can be tuned, and the undesired formation of the ketal can be controlled. The isomerisation of fumarates (Z‐isomer) to maleates (E‐isomer) is a gold‐catalysed process that can be conducted in one‐pot. When
