Abstract

Treatment of dodec-6-yne with triallylmanganate in the presence of 1, 3, 5-trimethylbenzene provides (Z)-dodec-6-ene. An addition of D2O before quenching the reaction affords the corresponding dideuterated alkene. The result suggests the existence of the manganese– alkyne complex as an intermediate. Treatment of methyl propargyl ethers as alkynes with tributylmanganate generates propargylmanganese species. The reaction of non-2-ynyl ...
