We are reporting that the stereospecificity of cis-2-pentene's metathesis is much greater when the initiator is (C6H5)2C=W(CO)51 than when it is any other previously examined, that this high stereospecificity is similar to that shown by cyclic olefins, 3 and accordingly that no special mechanism is
The stereochemical course of the intramolecular carbenoid cyclopropanation reaction has been studied for the epimeric carbenoids 12a and 12b. In these reactions the terl-butyldimethylsilyloxy substituent serves as an internal stereochemical reference point. It was found that 12b cyclizes rapidly at
## Abstract Ab initio calculations of negatively charged symmetrical and unsymmetrical transition states of the S~N~2โฒ reaction indicate that due to electronic reasons and particularly Coulomb interactions the __anti__ transition state is generally more stable than the __syn__ transition state. The
