Introduction and background

The reaction of interest was first reported by Miyaura and co-workers in 1997 [1]. It was found that the addition of phenylboronic acid, a reagent pioneered for Pd-catalysed Suzuki-Miyaura cross-coupling, to simple a,p -unsaturated ketones was catalysed by Rh(I) complexes. 

The co-product of the addition of water to the 7r-oxo-allyl rhodium complex, 5, in THF at 25°C was suggested to be an (unobserved) hydroxy rhodium species which rapidly dimerises to give complex 7, a square planar /z-hydroxy dimer. This complex was easily identified by the high field shifts of the /z-hydroxy protons ( — 1.9 ppm) and its symmetry (a single Rh-coupled doublet is observed at 55 ppm in the 31P 1H NMR spectrum). The assignment was confirmed by independent synthesis [(S)-BINAP)Rh(/x-Cl)]2 reacted cleanly with KOH in aqueous THF to give 7, as did addition of (S) -BINAP to the conveniently prepared complex [Rh(/z-OH)(cod]2 (cod = 1,5-cyclo-octadiene).

Background and introduction to accident— Describes the operational environment occurring at the time of the accident, the precursor events that may have set up the situation to occur, and other relevant data that can help the reader understand the conditions at the time of the accident. 

To understand the history of microlithography and its importance, and to motivate the various advances relative to polymeric materials used in resists, a brief background and introduction to semiconductor microelectronics and the role of miaolithography in that industry are helpful. Although the invention of the first semicondudor transistor by William Shockley, John Bardeen, and Walter Brattain at Bell Labs in 1947 was an immensely important milestone, as recognized in part by a Nobel Prize awarded to them in 1956, it was really the invention of the first monolithic IC by Jack Kilby and Robert Noyce in 1960 that ushered in what people enjoy today as the era of modem miaoelecttonics. The integrated devices developed by Kilby and Noyce consisted of many solid-state...
