Viktor Ullmann (review)

Viktor Hamburger (1900-2001)

Viktor Hamburger [5] was an embryologist who focused on neural development [6]. His scientific career stretched from the early 1920s as a student of Hans Spemann [7] to the late 1980s at Washington University [8] resolving the role of nerve growth factor [9] in the life of neurons. Hamburger is noted for his systematic approach to science and a strict attention to detail. Throughout his life he...

Software Synthesis Procedures * Viktor Kuncak

Automated synthesis of program fragments from specifications can make programs easier to write and easier to reason about. To integrate synthesis into programming languages, software synthesis algorithms should behave in a predictable way: they should succeed for a well-defined class of specifications. We propose to systematically generalize decision procedures into synthesis procedures, and us...

The mechanism of the modified Ullmann reaction.

The copper-mediated aromatic nucleophilic substitution reactions developed by Fritz Ullmann and Irma Goldberg required stoichiometric amounts of copper and very high reaction temperatures. Recently, it was found that addition of relatively cheap ligands (diamines, aminoalcohols, diketones, diols) made these reactions truly catalytic, with catalyst amounts as low as 1 mol% or even lower. Since t...
