The authors wish to advise of errors in the above paper. In Table 3, footnote C should read 'Crude product contains 4-methylanisole or p-tolyl acetate.' In the left column of text on the same page as Table 3, the second last sentence should read 'When the para-substituted arylacetates 9b and 9c were employed, 4-methylanisole and p-tolyl acetate were detected by 1H NMR analysis of the crude reaction mixtures but no attempts were made to isolate these simple decarboxylation products.'
Novel alkylaluminium chloride promoted [2+2] cycloaddition reactions of styrenes with 1,4-naphthoquinones and bromoquinones: A facile route to orthoquinodimethane precursors

The first examples of a Lewis acid catalysed [2+2]cycloaddition between styrenes and naphthoquinones have been observed. The reactions of both methoxyl and acetoxylnaphthoquinones were both regio- and stereospecific. When m-methoxystyrene was employed a novel tetracycle was also formed, and by an unexpected mechanistic pathway. Extension to bromoquinones resulted ultimately in the formation of arylnaphthocyclobutenes, common precursors of the orthoquinodimethanes.
Photoaddition of Ethenes to 1,4-Naphthoquinone: Factors Influencing the Site of Reaction

1,4-Naphthoquinone undergoes photocycloaddition to a variety of electron donor and electron acceptor ethenes giving spirooxetanes and/or cyclobutane derivatives.The site of addition onto the quinone depends on the electron donor character of the ethene, w
