R. Resendes et al., SYNTHESIS, STRUCTURE AND CATIONIC RING-OPENING POLYMERIZATION (ROP) OF A STRAINED [2]CARBATHIOFERROCENOPHANE, Chemical communications, (9), 1998, pp. 1001-1002
The synthesis and cationic ring-opening polymerization of a novel [2]c
arbothiaferrocenophane is reported; the polymerization represents the
first cationic ring-opening polymerization of a metal-containing ring.
