RuClH(CO)(PPh 3 ) 3 -catalyzed cycloisomerization of δ-enallenes to afford the cyclized 1,3- and 1,4-dienes depending on the substrates and reaction conditions is described by reacting δ-enallenes in toluene at reflux.
A new procedure is developed for the estimation of minimum-variance performance bounds in multivariable feedback control systems. The algorithm used in this paper does not require any knowledge of the interactor matrix. Instead, it uses the first few Markov parameters of the plant (up to the delay order of the process) and a set of closed-loop operating data to estimate an expression for the outputs...
