14. This bonding mode is similar to one observed previously in a ruthenium dimer, but in that structure the external double bond coordinates to the second metal center. See: Kawano, H.; Narimatsu, H.; Yamamoto, D.; Tanaka, K.; Hiraki, K.; Onishi, M. Organometallics 2002, 21, 5526-5530.
15. 3-bonding mode is present in compound 1, and thiapentadienyl C1/C2/C3/C4/S1 may represent a "trapped" isomerization intermediate.
16. H3-H4 = 8.1 Hz, reported by Kloosterziel (ref 6a).
17. 3 does not.
18. As with potassium thiapentadienide, this reagent is synthesized from a cyclic precursor, 2,3-dimethyl-1,4-dihydrothiophene. Hence, the cis internal double bond is expected.
