Dimethyl ( )-(-)-3-rerr.-butyloxy-l-octynylalane 45 was therefore prepared from (S)-(-)-3-hydroxy-1 -ocyne 44 with isobutylene in methylene chloride, followed by lithiation and reaction with dimethylchloroalane. Condensation of all-c/s-cyclo-pentane-3,5-dibenzylepoxide with this reagent in toluene formed the mixture of diastereomeric butylethers 47a and 47b. [Pg.61]

An order of magnitude slower is a many-atom-exchange process which leads to finite values of Dj at all values of i. With most alkanes at lower conversions, Di s beyond f = 3 have values which differ by less than a factor of 2. There is a broad maximum at a value of i several below the total number of hydrogen atoms. Cycloalkanes exhibit a maximum in D at i equal to the total number of hydrogen atoms. The minimum value of Dj is at i equal to about 4 and it is much smaller than that at the maximum. There is no discontinuity between cyclo-pentane-ds and -de. [Pg.56]

A four-coordinate NbOL3 molecule resulted from the reaction of NbCl4(thf)2 and LiL = LiN(SiMe3)2 via oxygen abstraction from solvent thf. The low coordination number is imposed by the steric demands of the amido ligand.249 An equivalent structure resulted from reaction of MOCl3 with a lithiated aza-2,5-disila-cyclo-pentane ligand (125).250...
