A mild and high-yielding visible-light-promoted conversion of alkyl benzyl ethers to the alkyl esters or alkyl alcohols was developed. Mechanistic studies provided evidence for a radical chain reaction involving the homolytic cleavage of O-α-sp3 C-H bonds in the substrate as one of the propagation steps. We propose that α-bromoethers are key intermediates in the transformation.

The reductive homocoupling of carbonyl compounds and heterocoupling of a carbonyl compound with an alkoxysilane were both effected smoothly with triethylsilane in the presence of a catalytic amount of bismuth bromide (1-3 mol%) under mild conditions. This ether-forming reaction was successfully applied to the single-step preparation of novel crownophanes with olefinic or acetylenic linkages.

Zeolite-promoted benzylation of alcohols with benzyl chloride has been investigated.By use of a series of cation-exchanged zeolites, which have the same crystalline structure but different acid and base properties, it is confirmed that the cooperative function of acid sites and base sites of zeolite is required for the effective benzylation of alcohols, although both acid and base strengths are low.It is also found that alcohols show different reactivities in zeolite from those in solution depending on their molecular structures because the benzylation is promoted inside the narrow cavities of zeolite.
A NOVEL METHOD FOR THE PREPARATION OF SYMMETRICAL AND UNSYMMETRICAL ETHERS. TRITYL PERCHLORATE PROMOTED REDUCTION OF CARBONYL COMPOUNDS WITH TRIETHYLSILANE

, p. 743 - 746 (2007/10/02)
In the presence of a catalytic amount of trityl perchlorate, symmetrical ethers are prepared from aldehydes and triethylsilane, and unsymmetrical ethers are also obtained from carbonyl compounds, alkoxytrimethylsilanes and triethylsilane, in good yields, respectively.
BENZYLATION OF ALCOHOLS TO BENZYL ETHERS WITH ALKALI CATION EXCHANGED Y TYPE ZEOLITE
Onaka, Makoto,Kawai, Motomitsu,Izumi, Yusuke
, p. 1101 - 1104 (2007/10/02)
Benzylation of alcohols with benzyl chloride is found to proceed efficiently in the presence of alkali cation exchanged Y type zeolite in a non-polar solvent under neutral conditions.The effects in solvent and alkali cation of zeolite are studied.
