Results and discussion McMurry reactionKetones and/or aldehydes can be coupled to alkenes by reductive treatment under deoxygenation. This reaction was discovered in 1973/74 in several laboratories [18][19][20] and is usually reported nowadays as McMurry reaction 21-25).

Ferrocene-containing polymers were synthesized via addition reaction of 1 , 1'-dimercaptoferrocene (1) and l,l'-bis(2-mercaptoethyl)ferrocene (2) to various diolefinic monomers such as dimethacrylates, divinyl ethers, divinyl sulfones and others. The dithiol 1 was also used as a monomer in condensation reactions with bifunctional acid chlorides. The polymerization of propylene sulfide in the presence of 1 as a bifunctional initiator was found to lead to polymers with a single central ferrocene unit.
