✦ Synopsis

H20 7 H3 (4) + 2 [CO'Pcj--2 COI'PC + c1-+ c12c=c I + HC03-+ ( 3 ) c H3 C o P c = Cobalt phthalocyanine

Removal of the TCBOC group can be accomplished with the supernucleophilic cobalt(1)-phthalocyanine anion in methanol or a~etonitrile[~, '3 and with zinc in glacial acetic acid (see Table ); the yields of amine component are 66-94 %.

N-Terminal deprotection by lithium cobalt(1)-phthalocyanine also proceeds smoothly in the case of benzyl esters.
