The acetylenes possessing one and two 1-phospholyl groups were synthesized by reaction of the alkynyl Grignard reagents with the 1-chlorophosphole and converted to the corresponding phosphole sulfides. Reaction of the 1-phenylethynylphosphole sulfide with CpCo(CO)2 resulted in η4-complexation on the phosphole moiety. The structures of the di(1-phospholyl)acetylene disulfide and the [η4-(1-phenylethynylphosphole
