Trikittiwong, Piyarat,Sukpirom, Nipaka,Shimazu, Shogo,Chavasiri, Warinthorn
, p. 104 - 107 (2015/03/18)
FeOx-pillared clays (FeOx-pillared bentonite, FeOx-pillared hectorite and FeOx-pillared taeniolite) were synthesized by the intercalation of FeCl3 into clay interlayers and calcination. The synthesize

Phosphonium salts and aldehydes from the convenient, anhydrous reaction of aryl acetals and triphenylphosphine hydrobromide
Ramanathan, Mani,Hou, Duen-Ren
, p. 98 - 108 (2013/05/09)
The reactions of aryl acetals/ketals and triphenylphosphine hydrobromide gave the corresponding aldehydes/ketones and alkyl phosphonium bromides. This reaction was applied to convert acetals/ketals to the corresponding aldehydes/ketones under an anhydrous
Cu(OTf)2-catalyzed selective opening of aryl and vinyl epoxides with carbonyl compounds to give 1,3-dioxolanes
Krasik, Pavel,Bohemier-Bernard, Mathieu,Yu, Qing
, p. 854 - 856 (2007/10/03)
Copper(II) triflate catalyzes the ring-opening of aryl- and vinyl-substituted epoxides with various carbonyl compounds to furnish 1,3-dioxolanes under mild conditions. Alkyl- and alkoxycarbonyl-substituted epoxides remain unchanged under reaction conditio
Stereoelectronic effects in the DIBAL reduction of aryl-1,2-ethanediol benzylidene acetals
Gauthier Jr., Donald R,Szumigala Jr., Ronald H,Armstrong III, Joseph D,Volante
, p. 7011 - 7014 (2007/10/03)
Reduction of benzylidene acetal 8 with DIBAL-H selectively gave 4 in 89% yield. 1-Aryl-1,2-diol benzylidene acetals display unusual regioselectivity with electron withdrawing groups on the aryl group.
Transacetalation: a convenient, nonaqueous method for effecting the deprotection of isopropylidene and benzylidene derivatives of sugars
Andrews, Mark A.,Gould, George L.
, p. 141 - 148 (2007/10/02)
Sugar isopropylidene and benzylidene derivatives can be readily deprotected under nonaqueous conditions by treatment of a dichloromethane solution of the protected sugar with an excess of a sacrificial glycol in the presence of a catalytic amount of p-toluenesulfonic acid.The reaction is conveniently monitored by GLC, and the fully or partially deprotected product precipitates from solution.
N-Benzyl Pyridinium Salta as New Useful Catalysts for Transformation of Epoxides to Cyclic Acetals, Orthoesters, and Orthocarbonates
Lee, Sang-Bong,Takata, Toshikazu,Endo, Takeshi
, p. 2019 - 2022 (2007/10/02)
In the presence of catalytic amount of N-(4-methoxybenzyl)-2-cyanopyridinium hexafluoroantimonate, the reaction of a few epoxides with aldehydes, ketones, lactones, and carbonates efficiently afforded corresponding cyclic acetals, orthoesters, and orthocarbonates under mild conditions.
