The atom efficient phospha-Michael reaction between bis 4-methylphenyl phosphine oxide and several activated internal alkenes has been shown to occur under microwave irradiation without added solvent or catalyst. The alkenes used for this study were ethyl 4-nitrocinnamate, two chalcones ((E)-3-(4-methoxy-phenyl)-1-(4- nitrophenyl)-prop-2-en-1-one and (E)-1-(4-methoxyphenyl)-3-(3-nitro-phenyl)-prop-2- en-1-one), and 2-phenylmethylene-propanedinitrile. In the case of ethyl 4-nitrocinnamate, reaction with bis 4-methylphenyl phosphine oxide for sixty minutes at 130 °C yielded the desired phospha-Michael product in a 55% yield after purification. Varying the location of the nitro group on the phenyl rings of the chalcones did not seem to have a large effect on their reactivity. By NMR, both chalcones seemed to react to the same extent when the reaction times and temperatures were held constant. Interestingly, a phospha-Michael reaction was observed at a reaction temperature of 65°C for experiments involving 2- phenyl-methylene-propanedinitrile while the other substrates required a reaction temperature of 130 °C. Similar experiments were carried out with bis mesityl phosphine oxide and two internal alkenes: 2-phenylmethylene-propanedinitrile and ethyl-2-cyano-3- methyl-2-butenoate. These experiments did not yield any of the predicted phospha- Michael products, which suggest steric limitations to the Michael donor for this reaction.

Until recently the role of the public drinking house has been approached from elitist, folkloric and anecdotal perspectives. The work of a new generation of social historians, however, has raised the tavern’s profile in the academic consciousness and confirmed its position within the mainstream of social and cultural history. It is now recognized that an understanding of the centrality of public drinking to the development of both elite and popular culture is vital to studies of social behaviour. The study of taverns has also been at the forefront of emerging interest in the history of consumption and material culture, and has contributed to a richer understanding of economic history. Constructions of gender and identity are also visible through research into the patterns of behaviour and discourse in and around the public house. This four-volume reset edition presents a wide-ranging collection of primary sources which uncover the language and behaviour of local and state authorities, of peasants and town-dwellers, and of drinking companions and irate wives. The documents are translated and set in their social and historical context, providing a multidisciplinary collection that will be of great importance to scholars of all areas of social and cultural history of the early modern period. The vast majority of this material is published here for the first time, ensuring that the collection will open up new avenues of research. Volume 1 draws heavily from the Parisian police archives and includes inspectors’ reports, complaints by the general public and details of court cases to build a picture of drinking in early modern France. Volumes 2 and 3 address public drinking in the Holy Roman Empire through a variety of chronicles, civic ordinances, court records, travel reports and surveys of public houses. Volume 4 locates taverns within a broader analysis of America’s public houses, drawing on visual material as well as journal entries, business reports and newspaper articles. Each volume is accompanied by editorial introductions and is annotated to provide readers with a high-quality resource of scholarly material.
