Beschreibung

cis-2-Butene-1, 4-diol is used as a probe for studying isomerization versus hydrogenation and hydrogenolysis reactions. (DPCB-OMe) efficiently catalyzes cyclodehydration of cis-2-butene-1,4-diol with active methylene compounds to give 2-vinyl-2,3-dihydrofurans in good to high yields. Grubbs's cross metathesis of eugenol with cis-2-butene-1, 4-diol to make a natural product, an organometallic experiment.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
