Class Information
Number: 585/661
Name: Chemistry of hydrocarbon compounds > Unsaturated compound synthesis > By dehydrogenation > Using transition metal oxide, sulfide, or salt
Description: Subject matter in which the synthesis takes place in the presence of an oxide, sulfide, or a salt containing a metal in which an inner electron shell, rather than an outer shell, is partially filled. In the periodic table transition metals include elements 21 through 30 (scandium through zinc), 39 through 48 (yttrium through cadmium), 57 through 80 (lanthanum through mercury), and 89 through 103 (actinium through lawrencium).
