Studies on selective nucleophilic substitution reactions of [(cyclopentadienyl)(1,3-dichlorobenzene)M]+ PF6- complexes (M = iron, ruthenium)
摘要:
Reactions of [cyclopentadienyl)(1,3-dichlorobenzene)M]+PF6- complexes (M = Fe, Ru) with phenoxide nucleophiles were found to proceed with excellent selectivity under mild conditions to give products of monosubstitution. Using aminophenoxides, a preference for O-arylation was observed, while amino alcohols such as prolinol react selectively on nitrogen. Methodology for sequential selective displacement of both chlorides by different nucleophiles is reported.
