Pd-catalyzed allylative dearomatisation of naphthyl halides is shown to be feasible by employing Grignard reagents. The high reactivity of the nucleophile allows for fast reactions and low catalyst loading, while a plethora of successfully substituted compounds illustrate the broad scope. Five membered heteroaromatic compounds are also demonstrated to be reactive under similar conditions.

A KOtBu and ethyl acetate mediated efficient methodology has been developed for the acetylation of primary and secondary alcohols where ethyl acetate is the source of acetyl group. The reaction is fast, mild, efficient, and highly selective towards the primary alcohols.

Fluorescent conjugates of N-benzyloxycarbonyl protected γ-aminobutyric acid were prepared by coupling to its C-terminus several polyheteroaromatic, based on the oxobenzopyran skeleton (trivially known as coumarin) and polyaromatic labels, such as naphthalene and pyrene. Photophysical properties were evaluated, as well as their behaviour towards photocleavage by irradiation in MeOH/HEPES buffer solution (80:20), in a photochemical reactor at different wavelengths (254, 300, 350 and 419 nm), followed by HPLC/UV monitoring.
A simple method for deprotection of tert-butyldimethylsilyl ethers by using stannous chloride under microwave irradiation

A facile regeneration of hydroxy compounds from their tert- butyldimethylsilyl ethers in presence of stannous chloride under solvent free conditions using domestic microwave oven has been performed efficiently in a short period (5-6 min). The conversion using stannous chloride in ethanol or water for comparison of the efficiency has been described. The generality of the transformation has been confirmed by several examples.
Substituent effects on homolytic versus heterolytic photocleavage of (1-naphthylmethyl)trimethylammonium chlorides
Foster, B.,Gaillard, B.,Mathur, N.,Pincock, A. L.,Pincock, J. A.,Sehmbey, C.
, p. 1599 - 1607 (2007/10/02)
Singlet escited state rate constants have been measured for both the heterolytic and homolytic photocleavage of 3- and 4-methoxy and 3- and 4-cyano (1-naphthylmethyl)trimethylammonium chlorides, 6-10.The results are interpreted in terms of the meta effect or changes in charge distribution upon excitation and the competition between bond cleavage, electron transfer, and hydrogen atom transfer in the contact pairs resulting from the two types of cleavage.
Preparation of a series of substituted fluoromethylnaphthalenes
Dixon, Elisabeth A.,Fischer, Alfred,Robinson, Frank P.
, p. 2629 - 2641 (2007/10/02)
A series of 22 3- and 4-substituted 1-fluoromethylnaphthalenes have been synthesized.Details of practical procedures for the preparation of all intermediates are described, and physical properties for all of the substituted naphthalenes synthesized, and spectral parameters for 51 previously unknown compounds, are given.
