  η:η-Alkynyl-Bridged W−Si Complexes:  Formation, Structure, and Reaction with Acetone

  摘要：

  Reactions of (eta5-C5Me4R)(CO)2(MeCN)WMe (R = Me, Et) with HPh2SiCCtBu gave the novel alkynyl-bridged W-Si complexes, (eta5-C5Me4R)(CO)2W(mu-eta1:eta2-CCtBu)(SiPh2) (R = Me, Et), whose alkynyl ligands bridge the tungsten and silicon atoms in an eta1:eta2-coordination mode. The structures of these complexes were fully characterized, including X-ray crystallography. Treatment of (eta5-C5Me5)(CO)2W(mu-eta1:eta2-CCtBu)(SiPh2) with acetone resulted in acetone insertion into the silicon-alkynyl linkage followed by intramolecular C-H activation of the tBu group to give the chelate-type alkyl-alkene complex, (eta5-C5Me5)(CO)2W(eta1:eta2-CH2CMe2C=CHSiPh2OCMe2).

• Sodium triethylborohydride as a catalyst for the dehydrogenative silylation of terminal alkynes with hydrosilanes

  sodium triethylborohydride-catalyzed C(sp)–H bond silylation is reported. The reaction of aromatic and aliphatic alkynes with aromatic hydrosilanes and hydrosiloxanes proceeded in a highly selective manner to afford dehydrocoupling products. Competitive hydrosilylation of the terminal alkyne did not occur as a side-reaction. In view of the above it is remarkable that NaHBEt3 is commonly used as a reducing

  Novel eta(3)-silapropargyl/alkynylsilyl complexes Cp*(CO)(2)Mo(eta(3)-Ph(2)SiCCR) (3a, R = (t)Bu; 3b, R = (i)Pr) were synthesized by the reactions of Cp*(CO)(2)(MeCN)MoMe (1) with alkynylsilanes HPh(2)SiC[triple bond]CR. The structures of 3a and 3b were fully characterized by NMR spectroscopy and X-ray crystallography. The reaction of 3a with MeOH at room temperature gave the stable four-membered metallacycle

  Reaction of acetylide-silylene complex Cp*-(CO)(2)W(SiPh2)((CCBu)-Bu-t) (1a) with 4-(dimethylamino)-pyridine (DMAP) gave an equilibrium mixture of DMAP-stabilized silylene acetylide complexes trans- and cis-Cp*-(CO)(2)W(SiPh2 center dot DMAP)((CCBu)-Bu-t) (trans-4 and cis-4). The corresponding reaction using Cp*(CO)(2)W(SiPh2)(CCSiMe3) (2) produced the novel DMAP-coordinated silenylcarbyne/silylvinylidene complex Cp*(CO)(2)W[CC(SiPh2 center dot DMAP)(SiMe3)] (6a) as a major product, which was equilibrated with trans- and cis-Cp*(CO)(2)W(SiPh2 center dot DMAP)(CCSiMe3) (trans-5a and cis-5a) via silylene/silyl migration. The novel structures of cis-4 and 6a were revealed by X-ray crystallography. A mixture of 2 and pyridine exhibited interesting temperature-dependent NMR spectral changes, indicating the formation of trans- and cis-Cp*(CO)(2)W(SiPh2 center dot py)(CCSiMe3) (trans-5b and cis-5b) and Cp*(CO)(2)W[CC(SiPh2 center dot py)(SiMe3)] (6b) at low temperature, while a mixture of la and pyridine showed no such spectral changes.
