Oxidative Addition to Palladium(0) Made Easy through Photoexcited-State Metal Catalysis: Experiment and Computation

Hydroacenes Made Easy by Gold(I) Catalysis

A novel strategy for the synthesis of partially saturated acene derivatives has been developed based on a Au(I) -catalyzed cyclization of 1,7-enynes. This method provides straightforward access to stable polycyclic products featuring the backbone of the acene series, up to nonacene.

Synthesis of Barbaralones and Bullvalenes Made Easy by Gold Catalysis

The gold(I)-catalyzed oxidative cyclization of 7-ethynyl-1,3,5-cycloheptatrienes gives 1-substituted barbaralones in a general manner, which simplifies the access to other fluxional molecules. As an example, we report the shortest syntheses of bullvalene, phenylbullvalene, and disubstituted bullvalenes, and a readily accessible route to complex cage-type structures by further gold(I)-catalyzed ...

Transcendental and Algebraic Computation made Easy: Redesign of Core Library

Expression packages constitute a key technique for achieving the fundamental goals of Exact Geometric Computation (EGC). In this paper, we address the redesign of the Expression Package in the Core Library, addressing the following issues: • Transcendental computation: the current library is developed for algebraic computation but there is need for transcendental functions in many applications....

Concurrent Programming Made Easy

The task of programming concurrent systems is substantially more difficult than the task of programming sequential systems with respect to both correctness and efficiency. In this paper we describe a constraint-based methodology for writing concurrent applications. A system is modeled as: (a) a set of processes containing a sequence of “markers” denoting the processes points of interest; and (b...
