n-Alkyl arenes were prepared in a one-pot tandem dehydrogenation/olefin metathesis/hydrogenation sequence directly from alkanes and ethylbenzene. Excellent selectivity was observed when (tBuPCP)IrH2 was paired with tungsten monoaryloxide pyrrolide complexes such as W(NAr)(C 3H6)(pyr)(OHIPT) (1a) [Ar = 2,6-i-Pr2C 6H3; pyr = pyrrolide; OHIPT = 2,6-(2,4,6-i-Pr 3C6H2)2C6H3O]. Complex 1a was also especially active in n-octane self-metathesis, providing the highest product concentrations reported to date. The thermal stability of selected olefin metathesis catalysts allowed elevated temperatures and extended reaction times to be employed.
RINGOEFFNUNG UND METALLIERUNG VON 1,1-DIMETHYL-2-PHENYL-SILACYCLOPENTAN UNTER DEM EINFLUSS VON METHYLLITHIUM IN TETRAHYDROFURAN

In contrast to 1-phenylethyllithium, which reacts as a base, methyllithium attacks the silicon atom of 1,1-dimethyl-2-phenyl-silacyclopentane (7) as a nucleophile whereby ring-opening takes place presumably via an ate-complex intermediate.The primarily fo
