title: Orthomercurated and cycloaurated derivatives of the iminophosphorane Ph3P NPh

authors: Brown, Samuel D.J.

subjects: Iminiphosphorane

abstract: Ortho-lithiation of Ph3P NPh followed by reaction with HgCl2 gave good yields of [Hg{C6H4(PPh2 NPh)-2}Cl], 3, which was characterised spectroscopically and by an X-ray crystal structure determination. This is an isomer of the product of direct mercuration of Ph3P NPh which occurs on the N-bonded phenyl ring [J. Vicente, J.A. Abad, R. Clemente, J. Lopez-Serrano, M.C. Ramirez de Arellano, P.G. Jones, D. Bautista, Organometallics, 22 (2003) 4248]. Transmetallation of 3 with [AuCl4]− gave the corresponding cycloaurated complex [Au{κ2-C,N-C6H4(PPh2 NPh)-2}Cl2], with a five-membered metallocyclic ring incorporating four different elements.

title: Jumble Java Byte Code to Measure the Effectiveness of Unit Tests

authors: Irvine, Sean A.

subjects: computer science

abstract: Jumble is a byte code level mutation testing tool for Java which inter-operates with JUnit. It has been designed to operate in an industrial setting with large projects. Heuristics have been included to speed the checking of mutations, for example, noting which test fails for each mutation and running this first in subsequent mutation checks. Significant effort has been put into ensuring that it can test code which uses custom class loading and reflection. This requires careful attention to class path handling and coexistence with foreign class-loaders. Jumble is currently used on a continuous basis within an agile programming environment with approximately 370,000 lines of Java code under source control. This checks out project code every fifteen minutes and runs an incremental set of unit tests and mutation tests for modified classes. Jumble is being made available as open source.
