Improving backward stability of Sakurai-Sugiura method with balancing technique in polynomial eigenvalue problem
No full textsummary:One of the most efficient methods for solving the polynomial eigenvalue problem (PEP) is the Sakurai-Sugiura method with Rayleigh-Ritz projection (SS-RR), which finds the eigenvalues contained in a certain domain using the contour integral. The SS-RR method converts the original PEP to a small projected PEP using the Rayleigh-Ritz projection. However, the SS-RR method suffers from backward instability when the norms of the coefficient matrices of the projected PEP vary widely. To improve the backward stability of the SS-RR method, we combine it with a balancing technique for solving a small projected PEP. We then analyze the backward stability of the SS-RR method. Several numerical examples demonstrate that the SS-RR method with the balancing technique reduces the backward error of eigenpairs of PEP
Asymmetric counteranion-directed catalytic hosomi-sakurai reaction
No full text[EN] Counteranion control enables the enantioselective, organo Lewis acid catalyzed Hosomi¿Sakurai reaction of (hetero)aromatic aldehydes and allylsilanes using an easily handled disulfonimide precatalyst (see scheme). The key to the success of this system is to turn the usually undesired silylium ion catalysis into the desired catalytic regime and pair the cation with an enantiopure disulfonimide anion, thereby applying the concept of asymmetric counteranion-directed catalysisWe thank Melanie Gossens for technical support. Furthermore, help from our analytical departments, especially our GC and MS facilities is gratefully acknowledged.
