Bond breakage route

edit

Breaking C-O bonds is not theory - but reality. I think that Dye's earlier cmpds were unstable becauase of reductive cleavage of the ether linkages in the cryptand. Benzyl ehters have long been known to break with Na, I think.--Smokefoot 05:07, 9 August 2006 (UTC)Reply

About First Alkalide

edit
It was actually [Na(2,2,2-crypt)]+Na, first prepared by James L. Dye and his colleagues in 1974 at Michigan State University:

Hydrogen alkalide

edit

Has a similar hydrogen alkalide based on cryptands been synthesized? Does someone know if there are some reports on its synthesis?--188.26.17.81 (talk) 18:29, 7 November 2015 (UTC)Reply
