[Ru3(CO)12] react. Similarly S–C7H7 bond cleavage is predominant in reactions of known C7H7SR-7 (R = Me or Ph) and new C7H7SBut-7 (from [C7H7][BF4] and Na[SBut]) with a variety of metalcarbonyls. Only [Fe2(CO)6(µ-SR)2] is obtained with [Fe2(CO)9], and [Mo2(CO)2(µ-SBut)2(η-C5H5)2] with [Mo2(CO)6(η-C5H5)2], but from [Ru3(CO)12] complexes, [Ru3(CO)6(µ3-SBut)µ3-(η7-C7H7)}] and [Ru2(CO)4(µ-SR)µ-(η7-C7H7)}](R
化合物C 8 H 7 SMe是通过用MeSCl处理环辛基戊烯基锂制备的。与[Fe 2(CO)9 ]反应得到三羰基铁配合物[Fe(CO)3(C 8 H 7 SMe)]和反式-[Fe 2(CO)6(C 8 H 7 SMe)];前者似乎经历了这种单取代的环辛八烯配合物的特征性振动通量运动,而后者则是非通量的。硫-C 8 H ^ 7键断裂也很明显,在[形成Fe 2(CO)6(μ-SME)2 ]和[铁4(CO)12(μ 4 -S)(μ-SME)2,和的双环octatetraenyl]当C 8 ħ 7 SME和的[Ru 3(CO)12 ]反应。类似地š-C 7 H ^ 7键断裂是主要的已知的C反应7 ħ 7 SR-7(R = Me或PH)和新的C 7 ħ 7 SBU吨-7(从[C 7 H ^ 7 ] [BF 4 ]和Na [SBu t ])以及各种金属羰基化合物。仅[Fe 2(CO)6(μ-SR) 2

Inexpensive cycloheptatriene is regiospecifically converted to all three phenylsulfonyl substituted cycloheptatrienes. Epoxidation of these materials with achiral reagents is shown to be relatively regiospecific. Reasonable levels of enantiomeric excess (similar to 63,78%) are achieved by Sharpless asymmetric dihydroxylation of a pair of 3-substituted trienes. Crystallization of these sulfones provides the diols in enantiomeric excesses greater than 90%. (C) 2000 Published by Elsevier Science Ltd.
