The reactions of chloroethynylphosphonates with aromatic secondary aminomalonates occur as classic nucleophilic substitution of chlorine atom at the sp-hybridizied carbon atom to form new phosphorylated 2-arylaminomalonates, diethyl esters of 2-(diethoxyphosphorylethynyl)-2-arylaminomalonic acids. Nonobservance of chemo- and regioselectivity was revealed when using cyclohexyl- and benzylaminomalonates

The borontrifluoride diethyl etherate catalyzed intramolecular cyclization of diethyl 2-(dialkoxyphosphorylethynyl)-2-arylaminomalonates afforded a series of novel 3-phosphonylated indoles, diethyl 2-[3-(dialkoxyphosphoryl)-1H-indol-2-yl]propanedioates. Decarboxylation of the latter compounds resulted in the formation of ethyl 2-[3-(dialkoxyphosphoryl)-1H-indol-2-yl]acetates.
Market Solutions for Social Problems: Working-Class Housing in Nineteenth Century London

This article shows how model dwellings companies were able to offer a solution to the 'housing problem' by profitably providing decent working-class accommodation in nineteenth-century London. Despite their success, a conjuncture of economic circumstances, ideological change, and public crowding-out led to the marginalization of model dwellings companies. This experiment to provide a market solution to a social problem represents a nineteenth-century form of ethical investment which has not been accommodated within the historiography of the development of the welfare state.
