Under aprotic conditions, Cr(CO) 5 CNCCl 3 ( 1 ) reacts with triphenylphosphine in the presence of aromatic aldehydes or ketones to give the α-chloroalkenylisocyanide complexes cis ( Z )- and trans ( E )-Cr(CO) 5 CNCCl CRR′ {R = H, R′ = 4-C 6 H

The X-ray crystal structures of four 1-(halodimethylsilylmethyl)-2-quinolinones have been measured and used to model the reaction profile for nucleophilic substitution at silicon. Similar structural correlations have been performed in solution, the p

Silylnitrilium (6) and Silyloxonium (7) ions have been synthesized by reaction of 2,3-benzo-1,4,5,6,7-pentaphenyl-7-silanorbornadiene, 4, with trityl tetrakis(pentafluorophenyl)borate in benzene in the presence of acetonitrile and diethyl ether, resp

Equimolar amounts of trichlorovinylsilane (9), lithium-tert-butyl, and 1,3-enynes were reacted to yield the corresponding isomeric silacyclobutanes and silacyclobutenes competitively. As reaction pathway the mixture 9/tBuLi is discussed to give a sil

Equimolar mixtures of trichlorovinylsilane and t-BuLi (1) were reacted with different vinyl ethers, CH2CH−OR (R = Et, n-Pr, n-Bu, i-Bu, t-Bu), to yield the silacyclobutanes 2−6. NMR spectroscopic investigations showed the addition of the formal s

Two different synthetic routes for the formation of sodium phenylsiloxanolate (SPS) have been developed: (i) the cleavage of oligo(phenylsilsesquioxane), OPSSO, by NaOH in n-butyl alcohol and (ii) the reaction of phenyltri-n-butoxysilane, PhSi(n-BuO)

Catalytic hydrogenation of olefins containing functionalized silicon groups affords the saturated products in good yields. Chloro and alkoxy substituents at the silicon atom remain unaffected and, in the case of heterocyclic compounds, the cyclic or
