Agwada, Vincent C.,Awachie, Peter I.
, p. 779 - 780 (1982)
The isolation of benzhydrol and its ether in conjunction with N-formylbenzhydrylamine in the Leuckart reaction of benzophenone is reported; it is postulated that this alcohol is a possible intermediate in the reaction.
Room temperature reactions of XeF2 with phenyl substituted alcohols

, p. 4355 - 4356 (1993)
Benzyl alkohol and its analogues with a non-activated benzene ring are transformed to fluoromethoxy derivatives by reaction with XeF2. The same reaction with diphenyl methanol gives di diphenylmethylether, while 2-phenyl-2-propanol transforms to 2,4-diphenyl-4-methyl-1-pentene.

An expedient, efficient, economical, environmentally benign, and solvent free amidation protocol of benzhydrols with less reactive nitrogen nucleophiles assisted by propylphosphonic anhydride (T3P) under microwave irradiation has been developed. The methodology has been deployed for a wide range of heterocycles and electron-withdrawing & electron-donating groups. The protocol resulted in good to excellent yields under the given conditions (26 examples, 68-93% yield).

Paragraph 0073-0082, (2021/07/28)
The invention provides a borane-catalyzed symmetric ether synthesis method, which is characterized in that alcohol is used as a raw material, and under the catalysis of B(2,6-Cl2C6H3) (p-HC6F4) 2, etherification reaction is carried out through intermolecular dehydration to generate ether. The reaction process is simple, mild, pollution-free and efficient.

Monoallylation and monoalkylation of diketones and β-keto esters with allylic and benzylic alcohols catalysed by [Cp*Co(CH3CN)3][SbF6]2(I) are reported. The method does not require any additive and affords regioselective products. The mechanistic investigations were done byin situ1H NMR spectroscopy as well as control experiments. It has been shown that reactions proceedviaη3-allyl complex formation or ally ether intermediate. The alkylation takes placeviaonly ether intermediate. The resulting allylated and alkylated products have been used for the synthesis of eleven new trisubstituted pyrazoles and one pyrazolone.

The deoxygenation of tertiary and secondary alcohols to give the corresponding alkanes is conventionally performed using an organosilane and a strong acid. In this study, a deoxygenation method was developed for tertiary and secondary alcohols, using trimethylsilane and trimethylsilyl iodide generated in situ from sodium borohydride and trimethylsilyl chloride, and trimethylsilyl chloride and potassium iodide, respectively. With our method, tertiary and secondary alcohols, which provided stable carbocations, were converted into the corresponding alkanes. This paper also presents the optimization of the reaction conditions, the reaction mechanism, as well as the scope and limitations of the method.

Paragraph 0071-0074, (2020/12/29)
The invention discloses a method for synthesizing ether by catalyzing alcohol through trimethyl halosilane. According to the method, under the conditions of air or nitrogen atmosphere, no solvent andno transition metal catalyst, an alcohol compound is directly used as a raw material, trimethyl halosilane is used as a catalyst, and symmetric or asymmetric ether is synthesized through one-step selective dehydration reaction. According to the method, the use of strong acid, strong base and organic primary halides with high toxicity, instability and higher price is avoided, the synthesis steps are shortened, the synthesis efficiency is improved, the reaction has good selectivity, and a target ether product can be obtained preferentially.
Switchable iridium hydride catalysts for controlling selectivity of alcohol oxidation
Albrecht, Martin,Olivares, Marta
, (2020/05/25)
Novel pyridyl-triazolylidene iridium(III) hydride complexes have been synthesized through modification of the analogous iridium chloride complexes. The dehydration of alcohols was used to probe the catalytic potential of the iridium chloride compounds and the influence of the electronic modification on the pyridyl-triazolylidene ligand scaffolds. The incorporation of electron donor substituents on the triazolylidene heterocycle considerably enhanced the catalytic activity of the coordinated iridium center towards the catalytic dehydration of alcohols. Moreover, the iridium hydride compounds are switchable catalysts that perform either alcohol dehydration or dehydrogenation. Their selectivity was predictably triggered by the presence or absence of HPF6 in the catalytic reaction.
