in an environmentally benign solventless system, alcohols are rapidly oxidized to carbonyl compounds using hexamethylenetetramine-bromine on wet alumina under microwave irradiation.

Abstract The direct and selective C(sp 3 )-H functionalization of cycloalkanes alkanes is a highly useful process in organic synthesis owing to the low-cost starting materials, high step atom economy. Its application asymmetric catalysis, however, has been scarcely explored. Herein, we disclose our effort toward this goal by incorporation dual photocatalysis chiral nickel catalyst commercially ...
