Remote Deprotometalation-Iodolysis of N,N-Diisopropyl-2-trimethylsilylferrocenecarboxamide: A New Route Toward 1,1′-Disubstituted Ferrocenes

Abstract

The 1,1′-disubstitution is currently the most frequent substitution pattern encountered in the ferrocene series. Here an original access based on the remote deprotometalation of N,N-diisopropyl-2-trimethylsilylferrocenecarboxamide is reported. The key intermediate, 1′-iodo-N,N-diisopropylferrocenecarboxamide, was prepared in multiple grams and was further functionalized toward fifteen 1′-substituted iodoferrocenes.

Key words

ferrocene - 1,1′-disubstitution - carboxamide - remote functionalization - functional group manipulation
