Dip in! A Rh/dippf catalyst generates aldehyde‐derived enol boranes at ambient temperature by isomerization of allyloxy‐ and homoallyloxyboranes. A one‐pot isomerization/cross ‐ aldol sequence provides aldehyde–aldehyde adducts in good yield with syn  selectivity. Direct use of primary allylic and homoallylic alcohols was also achieved.
