Whereas the addition compounds of boron trichloride with dimethyl ether and with diethyl ether are stable at room temperature, BCls eflfects cleavage of tetrahydro-furane, and it reacts with ethyleneglycol dimethyl ether even at 0° with evolution of methyl chloride, presumably with formation of the mono- and dichloroboronates ... 

Scheme 2.136 Perfluoroalkylation with MeaSiCFa and its homologue Me3SiC2F5 by nucleophilic substitution of alkyl triflates (glyme = ethyleneglycol dimethyl ether) [90].

The bis(77-cyclopentadienyl)zirconium dichloride has been synthesized by a variety of routes and a variety of authors. It can be recovered from reaction systems of zirconium tetrachloride and sodium cyclopentadienide in tetrahydrofuran or ethyleneglycol dimethyl ether 89, 194, 343, 471) or with lithium cyclopentadienide 472) in place of the sodium compound. The hafnium compound was prepared in a similar manner 343, 471). In general, the residue obtained upon evaporation of the solvent is extracted with chloroform and the product from the extraction is recrystallized from benzene. The dichloride was also prepared 451) by the continuous recirculation of cyclopentadiene vapor through a bed of ZrCl2 at 270°-350°C. Another route to the chloride is the reaction of zirconium tetrachloride with cyclopentadienylmagnesium chloride 559) in benzene yet another involves the reaction of zirconium tetrachloride and cyclopentadiene in ethylamine as the solvent at room temperature 367). 

Contrast the effect of heat on mercuric benzoate, when substitution of the aromatic ring ortho to the carboxyl group occurs. Mercuric tri-chloroacetate decar Wylates so rapidly that it has not yet been isolated. Bis(trichloromethyl)mercury was obtained in good yield by the reaction of sodium trichloroacetate and mercuric halides in ethyleneglycol-dimethyl ether ...
