Abstract
The doubly homologated meso-octaethylporphyrinogen 1, containing two pyridine and two pyrrole rings in cis arrangements, allowed the synthesis of highly reactive vanadium(III) organometallics, via the intermediacy of 2, [Et(8)(m-MeC(5)H(2)N)(C5H3N)(C4H2N)(2)Li-2(THF)(2)], and 3, [Et(8)(m-MeC(5)H(2)N)(C5H3N)(C4H2N)(2)V-Cl]. This latter complex has been converted to the corresponding [V-Me] derivative [Et(8)(m-MeC(5)H(2)N)(C5H3N)(C4H2N)(2)V-Me], which undergoes a facile carbonylation to 5, Et(6)(m-MeC(5)H(2)N)(C5H3N)(C4H2N)(2)V-OC(CEt(2))(Me)]. The intermediate eta(2)-acyl derivative thus found displayed an unusual carbenoid reactivity inserting into a C-C bond.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
