    • The wording in reference [10 b] is ambiguous, but the statement within the reference that low-oxidation-state metal carbenes have not initiated olefin metatheses and statements in other of Schrock's writings imply the intended meaning: that the only Mo or W initiators of olefin metatheses are in a high oxidation state.

The cis stereoselectivities for cyclopentene, cyclodecene, and cyclododecene were 55, 20, and 20%, respectively. Cycloheptene gave no polymer. Schrock molybdenum carbenes gave polymers whose double bonds were mainly trans.

    • 1H NMR spectrum of the metal carbene changed significantly and only 2 min were required for the metal carbene in toluene at 25°C to equilibrate 2-pentene, 2-butene, and 3-hexene. After 24 h, 80% of the initial metal carbene was converted into the presumed propylidene analogue, and after another 15 h all the metal carbenes had decomposed, which seems odd.
