Controlling Catalyst Behavior in Lewis Acid-Catalyzed Carbonyl-Olefin Metathesis.

Lewis acid-catalyzed carbonyl-olefin metathesis has introduced a new means for revealing the behavior of Lewis acids. In particular, this reaction has led to the observation of new solution behaviors for FeCl that may qualitatively change how we think of Lewis acid activation. For example, catalytic metathesis reactions operate in the presence of superstoichiometric amounts of carbonyl, resulting in the formation of highly ligated (octahedral) iron geometries.

Understanding disability in healthcare: exploring the perceptions of parents of young people with autism spectrum disorder.

How autism spectrum disorder (ASD) is understood (i.e., as a medical problem or natural human variation) has profound implications for how healthcare services are designed and delivered.
