SUMMARY

The reaction between benzaldehyde (PhCHO) and sulfur tetrafluoride (SF4) involves the participation of lone pairs on oxygen and pi electrons in the benzene ring. The mechanism indicates that the positive carbon is stabilized by the benzene ring and oxygen, while the sulfur atom acquires a negative charge due to electron accumulation. Understanding the stability of the sulfur and the charge distribution is crucial for elucidating the reaction mechanism. This analysis provides a clear pathway for constructing the reaction mechanism effectively.

There is reaction between
PhCHO + SF4
I tried to make the mechanism but I stuck .

I'm not quite sure what PhCHO is, it seems as though it is benzaldehyde. If that's the case let's look at your electrons that can participate in bonding. You have two lone pairs on an oxygen, two electrons in a pi bond, and 6 pi electrons in resonance in your ring. These are the only electrons that will be able to form a bond and given the reactivity of benzene pi bonds, it's unlikely that they will be involved. Also think about you the stability. The positive carbon is fairly stable due to the benzene ring on one side and oxygen on the other.
 
Your last compound is wrong. The sulphur shall have a -ve charge due to accumulation of another pair of electrons and the carbonyl carbon shall have +ve charge. That should help you get the mechanism. Post that, think about the stability of the sulphur and how it can become more stable.
