✦ Synopsis

Molybdenum complexes / Peroxo complexes / Catalysis / Olefin epoxidation / Proton transfer NMR studies of the reaction of complexes of the type (L-L ) M O O ( O ~) ~

(L-L = bidentate ligand) with strong Brensted and Lewis acids prove that protons are transferred preferentially to an q2-peroxo and not to the 0x0 ligand. This behavior in proton transfer reactions is one critical point of the catalytic activity of such complexes in olefin epoxidation. EH calculations on the model complex (NH3)2M00(02)2 support the spectroscopic investigations.

The synthesis of the spiro[4.5]decane terpene skeleton from methoxy [1] and hydroxy substituted arenes has been stimulated by the interest in naturally occuring sesquiterpenes like spirovetivanes, acorones or alaskanes [1b,3] and their analogues. Among these methods is Nagao's approach [4] that uti

## Abstract The addition reaction of dibutylphosphane oxide [Bu~2~P(O)H] with alkynes proceeds efficiently in the presence of palladium‐chelating phosphane–Brønsted acid catalyst systems. Terminal alkynes afford branched‐structured products selectively. On the other hand, the same reaction using mo
