In this case, have you done this coupling reaction? For example, if I use dioxane, should I refine it? Maybegjj (intra-station contact TA) analysis is almost pure. This kind of reaction is much more than maybegjj (in-station contact TA):) The influence of catalyst is also quite great.

I basically use PD (OAC) 2 and PPH3.

Commonly used Pd(PPh3)4,

In the case of alkali, Et3N, K2CO3

Alkali needs to be added. I used Pd(OAc)2, tri-o-methylphenyl phosphorus and triethylamine as the base.

I tried several times, but nothing worked.

Toluene will do. If there is aldehyde, pay attention to the choice of alkali. Wild vanadium? Aybegjj (station contact TA):D turns black to prove the reaction. Yiyiweiyi (in-station contact TA) has used triethylamine as the solvent, or it can be: Ddafeizei (in-station contact TA) originated in Maybegjjat201-01665438.
