text: Amidines are a ubiquitous class of bioactive compounds found in a
wide variety of natural products; thus, efficient strategies for their preparation
are in great demand. Herein, a novel protocol is reported for the synthesis of
amidines based on PIII/PVO redox catalysis.
This two‐step, one‐pot approach involves the activation of amides via PIII/PVO
catalyzed in situ formation of imidoyl chloride intermediates which are directly
converted upon reaction with amines into the corresponding amidines. Instead of
traditionally used toxic and corrosive chloride sources, hexachloroacetone (HCA)
is successfully employed as a halide source. The reaction proceeds with low catalyst
loading (2 mol%) in BuOAc as the solvent. Under the optimized conditions, 20 amidines
are prepared in yields up to 99%. A feasible mechanism is proposed based on experimental
results. The synthetic potential of this method is evaluated in the preparation
of the tyrosine kinase inhibitor (TKI) Erlotinib.

text: This article investigates forms of address, in particular the T/V distinction
in German, in conversational interviews with German-speaking immigrants to English-speaking
Canada and their descendants. From among 77 interviews conducted in two urban
areas in Canada, we discuss instances of both the interactional use of and metalinguistic
comments on forms of address. Our analysis is largely guided by conversation analysis
and interactional sociolinguistics (e.g. Goodwin & Heritage 1990). Using Clyne,
Norrby and Warren’s (2009) model of address as a backdrop, we investigate the
construction of group identity and group socialization through the lens of positioning
theory (e.g. van Langenhove & Harré 1993; Dailey-O’Cain & Liebscher 2009). This
combination of analytical tools can explain shifts in both usage of and attitudes
toward the T/V distinction that cannot be explained through language attrition
arguments alone.

text: Am Beispiel bolivianischer Migrantinnen in der Global City Buenos Aires wird
das Phänomen der Feminisierung der Migration in Lateinamerika und dessen Bedeutung
für die Konstitution translokaler sozialer Räume untersucht. Im Mittelpunkt einer
{\glq}dichten Beschreibung’ pluri-lokaler Alltagswelten stehen dabei ökonomische
Netzwerke und translokale Lebensentwürfe von Arbeiterinnen in illegalen Textilsweatshops
und Frauen der Töchtergeneration. Analysiert werden einerseits die alltagsweltlichen
sozialen Praktiken von Migrantinnen, die zu einer Kon-stitution eines translokalen
und kulturell hybriden Raumes zwischen den beiden Nationalgesell-schaften Bolivien
und Argentinien Raumes beitragen und andererseits Prozesse und Dynamiken der Neuaushandlung
von ethnischen Identitäten in einem solchen Raum. Probing into the lives of female
Bolivian migrants in the global city Buenos Aires, this empirical research explores
feminisation of migration in Latin America analysing its significance for the
constitution of translocal social spaces. Applying {\grq}thick description’ to
the migrants’ pluri-local life worlds, the study closely examines how Bolivian
women in Buenos Aires, partly working in illegal sweatshops and partly second
generation migrants, establish economic networks and set up their translocal life
plans. Thus the analysis of the migrants’ everyday social practices, such as work
and leisure, yields insight not only into the constitution of a translocal and
cultur-ally hybrid social space between the two countries, but also into dynamics
of re-negotiation of ethnic identities within this space.
