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

A new alkyne protecting group, trispyrazolylborateplatinum(methyl) (TPM), that can tolerate various reaction conditions and is particularly useful for electron-deficient acetylenes allows for synthetic manipulations of polyfunctional acetylenes. This

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

Complex 1 undergoes H/D scrambling in methanol without concomitant liberation of either methane or dihydrogen (k(H)/k(D) = 0.76, 55 degrees C). The measured isotope effect was proposed to directly relate to the initial reductive coupling step in redu

The integrins alpha vbeta3 and alpha vbeta5 and the membrane-spanning surface protein aminopeptidase N (APN) are highly expressed in tumor-induced angiogenesis, making them attractive targets for therapeutic intervention. Both integrins and APN recog

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
