Reaction of the strongly electrophilic borane trans -pentenyl-B(C 6 F 5 ) 2 ( 5 ) with TEMPO gave the 2:1 addition product (C 6 F 5 ) 2 B( ONHR 2 ) CH CH CH(ONR 2 )-C 2 H 5 ( 8 ), (NR 2 = tetramethylpiperidinyl). It is thought to be formed by TEMPO a

B(C6F5)2-containing boryldienes 4 underwent the addition of two molar equivalents of TEMPO to give N,O-bonded four-membered heterocyclic products 7. The reaction is a metal-free example of the generation of reactive nitrogen-centered TEMPO radical de

Hydroboration of the conjugated enynes 1 a and 1 b with Piers' borane [HB(C6F5)2] gave the respective dienylboranes trans-2 c and trans-2 d. Their photolysis resulted in the formation of the dihydroborole products 3 c and 3 d. Both were converted to

The dienylborane 2a was prepared by regioselective alkyne hydroboration of the conjugated enyne 1a with Piers’ borane [HB(C6F5)2]. Its reaction with a series of acetophenone derived enamines 3 resulted in the formation of the strong enamine β-carb
