Abstract

Condensations of several a,a'-disubstituted 1,1'-ferrocenylenebis- carbinols (1) with mercaptoethanoic acid, 3-mercaptopropanoic acid or 3-acetylthio-2-methylpropanoic acid in the presence of tri- fluoroacetic acid have given the corresponding 1,1'-ferrocenylene- bisthiaaliphatic acids (2—4) in 49-90% yields. Reactions of acids 2-4 with trifluoroacetic anhydride yielded 15-29% of trans-2- oxa[3]ferrocenophanes (trans-8), 7-13% of [2,2]ferrocenophanes (9) and 8-15% of the ethanoferrocenylene oligomers (10). The mechanism of the reactions is discussed.
