4-tert-Butylcyclohexanol is rapidly converted to 4-tert-butylcyclohexanone with swimming pool bleach in a homogeneous reaction at room temperature. This process introduces students to a heterocyclic compound not normally discussed in the introductory

A rapid (normally 20 min to 2 h) and selective oxidation of secondary alcohols to ketones can be achieved using 0.4 equivalents trichloroisocyanuric acid and 1.2 equivalents pyridine at room temperature in ethyl acetate. A likely mechanism for the re

Organoactinide complexes of the type Cp*2AnMe2 (An = Th, U) have been found to be efficient catalysts for the hydroamination of terminal alkynes with aliphatic primary amines. The chemoselectivity and regioselectivity of the reactions depend strongly

Various organoactinides of the type Cp*2An(C⋮CR)2 (Cp* = C5Me5; An = Th, U) have been synthesized from the corresponding Cp*2AnMe2 complexes by addition of an equimolar amount or an excess of the corresponding terminal alkyne. Attempts to trap the

Organoactinides of the type Cp 2 * AnMe 2 (Cp * =C 5 Me 5 ; An=Th; U) are active catalytic precursors for the oligomerization of terminal alkynes HC≡CR (R=alkyl, aryl, SiMe 3 ). The regioselectivity and the extent of oligomerization depend strongly

Organoactinide complexes of the type Cp*2AcR2 (Ac = Th, U) catalyze the intermolecular hydroamination of terminal alkynes with aliphatic amines. The regioselectivity of the products can be tuned by the alkyne and the metal. Mechanistic studies shows
