Insertion reactions of acetylenes

The dinuclear rhenium disulfido complex with n,rj -S2 ligands (ReCp )2(/U-S2)2 (Cp =7j -C5Me4Et) (type IIa2 complex in Fig. 2) undergoes an insertion reaction of acetylene and ethylene into the S-S bond according to Scheme 57.

Topics of this section include 1,2-insertion reactions of acetylenes (b), olefins (c), allenes (d), oxygen (e), carbon dioxide (f), sulfur dioxide (g), sulfur trioxide (h), and nitric oxide (i). 

The insertion reactions of acetylene compounds with di-p-iodo-bis(lV, -dimethyl-l-naphthylamine-CAO-dipalladium form substituted heterocyclic products 7.29 with formation of palladium metal and the loss of one IV-methyl groups by refluxing in chlorobenzene (Eq. (7.26)) [79,82,84,85]. The heterocyclic compounds are synthesized directly by the reaction of iododimethylaminonaphthalenes with acetylenes in the presence of a catalytic amount of the 1-dimethylaminonaphthalene palladacycle, as shown in Eq. (7.27) [85].
