High reactivity but low stability<br />

<br />

Reactive without phosphine ligands at room temperature Inexpensive and easy to remove<br />

<br />

<br />

<br />

<br />

In many cases heating is required for the reactions to<br />

proceed.<br />

Formation of cationic complexes is unfavorable for metal<br />

exchange reactions.<br />

Effective to add some salts like LiCl for the reactions to<br />

proceed<br />

Only in a special case will the reactions proceed.<br />

Use of highly active catalysts<br />

Use of heteroaromatic chlorides (R = heteroaromatic rings)<br />

The order of the reactivity as follows:<br />

Electron-withdrawing group > electron-donating group<br />

<br />

<strong>Chemical</strong>ly stable and easy to handle<br />

Little by-product<br />

Expensive and hard to remove<br />

<br />

<br />

<br />

Improves oxidative addition<br />

Electron-withdrawing group is effective for oxidative addition. Improves reductive elimination<br />
