The free base 2,4-bis-(1′-dodecynyl)-deuteroporphyrin IX dioctylester, 6a, its Zn(II)complex, Zn-6a, its Cu(II)complex, Cu-6a, its Ni(II)complex, Ni-6a and a number of related compounds have been prepared. The synthesis of 6a involves as key steps the palladium-catalyzed coupling of β-diiodoporphyrin with dodecyne, and the acid-catalyzed esterification of the two propionic acid groups of deuteroporphyrin
1-difluoroethene (5) with sec-butyllithium in the presence of zinc chloride gave new fluorovinyl zinc reagents (12 or 13). These were distinguished by 19F NMR from trifluorovinylzinc chloride (7) or 1-chloro-2,2-difluorovinylzinc chloride (8) obtained by Normant’s group, via preliminary formation of fluorinated vinyllithium reagents by treatment of 4 or 5 with sec-butyllithium followed by addition of zinc
