- Chemical Transformations of Tetracyclo[3.3.1.13,7.01,3]decane (1,3-Dehydroadamantane): VII. Reaction of 1,3-Dehydroadamantane with Alkanediols and Amino Alcohols
-
The reaction of 1,3-dehydroadamantane with C2–C6 α,ω-alkanediols selectively afforded ω-(adamantan- 1-yloxy)alkan-1-ols in 87–94% yield. The reaction of 1,3-dehydroadamantane with ω-aminoalkan-1- ols (2-aminoethanol and 3-aminopropan-1-ol) gave mixtures of addition products through the oxygen and nitrogen atoms, which can be readily separated by fractional vacuum distillation or crystallization.

- N-Heterocyclic Carbene Complexes, Their Preparation And Use
-
Described are N-heterocyclic carbene complexes of the formula I, where n is 0 or 1, M is a metal atom containing group, R1 is selected from hydrogen alkyl, cycloalkyl, heterocycloalkyl, aryl and hetaryl, R2 is selected from hydrogen, alkyl, cycloalkyl, heterocycloalkyl, aryl and hetaryl, wherein R1 and R2 do not both stand for hydrogen. Furthermore, also described are methods for their preparation and their use as catalysts employed in a C—C, C—O, C—N or C—H bond formation reaction.

- Carbenes made easy: Formation of unsymmetrically substituted N-heterocyclic carbene complexes of palladium(II), platinum(II) and gold(I) from coordinated isonitriles and their catalytic activity
-
From palladium(II) or platinum(II) bis(isonitrile) complexes and from gold(I) isonitrile complexes, both easily available from simple precursors, the corresponding mono-N-heterocyclic carbene (NHC) complexes could be obtained selectively in good yields under very mild conditions. The reagents are simple β-chloroammonium salts in the presence of a weak base. Unsymmetric NHC complexes are accessible. Thus over only two steps from simple metal precursors a broad variety of NHC complexes is available, the method is ideal to quickly assemble catalyst libraries. The palladium complexes are active pre-catalysts in Suzuki cross-coupling even with the additional isonitrile ligand on palladium. Copyright

- DERIVATIVES OF ADAMANTANE. I. 2-HYDROXYETHYLAMINO DERIVATIVES OF ADAMANTANE
-
The reaction of 1-bromoadamantane with hydroxyalkylamines leads to the preferential formation of 1-(aminoalkoxy)adamantanes.The 2-hydroxyethylamino derivatives of the adamantane series were obtained by the reaction of ethylene oxide with the corresponding amines.
