The hydroboration reaction of the cyclopentadienes (I) and (II) yields the alcohols (III) which are oxidized under Swern conditions to give the corresponding 3‐alkyl‐3‐cyclopenten‐1‐ones (IV).

The addition of the (η3‐crotyl)titanocenes derived from (I) and (III) to the aldehydes (II) yields the anti‐ and syn‐adducts (IV) and (V).

Full gradient optimization at the RHF level of theory using 6‐31G* basis set leads, after correction for correlation energy differences up to MP3and inclusion of zero‐point vibrational energies, to a barrier to ring inversion of 75 kJ/mol for the tetrasila compound and of about 300 kJ/mol for bicyclo(1.1.0)butane.

The 2‐selenenylvinyl sulfones (I), prepared from the corresponding acetylenes by free‐radical selenosulfonation, react with the organocuprates, generated in situ from the lithium compounds (II), to form the substitution products (III).

The potential dependent etching and passivation behavior of silicon in KOH is investigated.
