Treatment of N‐heterocyclic silylene Si[N( t Bu)CH] 2 ( 1 ) and [(η 3 ‐C 3 H 5 )PdCl] 2 in toluene led to the formation of the mononuclear complex (η 3 ‐C 3 H 5 )Pd{Si[N( t Bu)CH] 2 }Cl ( 3 ), the silicon analogue to N‐heterocyclic carbene complex (η 3 ‐C 3 H 5 )Pd{C[N( t Bu)CH] 2 }Cl ( 2 ). Complex 3 was characterized with 1 H NMR and 13 C NMR. Investigation shows that (η 3 ‐C 3 H 5 )Pd{Si[N( t Bu)CH] 2 }Cl is an active catalyst for Heck coupling reaction of styrene with aryl bromides.
