When the Ottoman Empire defaulted on its public debt in 1875, British bondholders launched a campaign to win government intervention on their behalf. This article interprets the unprecedented success of this campaign as a matter of knowledge production. Mobilizing the newly established Corporation of Foreign Bondholders as a kind of 'centre of calculation', bondholders argued that they deserved assistance because of the unique size of the Ottoman default and the proportion of it that was held by British subjects. Yet neither of these numbers was easily calculated. In fact, influential bondholders worked closely with accountants and members of the Statistical Society to devise an accurate method for quantifying the Ottoman debt - and concluded that such a method did not exist. Historians of quantification and accounting have argued that the scientific status of nineteenth-century accounting depended on its disinterestedness. In the case of the Ottoman default, however, calculation was understood to be inseparable from material interest and political debate.

A (fluor)ry of activity: The transfer of an intact trifluoromethyl group from a hypervalent iodine reagent to an aliphatic alcohol occurs smoothly upon activation by zinc bis(triflimide). This constitutes a straightforward method for the preparation of trifluoromethoxy alkyl derivatives, compounds otherwise difficult to access.

Chelated amino acid ester enolates are excellent nucleophiles for palladium-catalyzed allylic alkylations. These enolates react rapidly at -78 degrees C and in general without isomerization of pi-allyl palladium complexes. Therefore, they are good candidates for mechanistic studies and regioselective reactions. Terminal pi-allyl palladium complexes are preferentially attacked at the least hindered position giving rise to linear products, as illustrated with several (E)-configured allylic substrates. Under isomerization free conditions the branched products are formed preferentially from the corresponding (Z)-allyl substrates. An interesting behavior is observed in the reaction of secondary allylic substrates. Aryl-substituted substrates show a significant memory effect which can be explained by an asymmetric pi-allyl complex. For alkyl-substituted substrates a strong dependence of the regioselectivity on the leaving group is observed, which can be explained by different conformations in the ionization step. Under isomerization free conditions the product ratio gives important information about this step.
