However, propargylic substitution reactions remain underdeveloped when compared to allylic substitutions.
However, their use in asymmetric dearomatization reactions is quite underdeveloped and, despite work by several research groups over the past several years, a general chiral aryl iodide catalyst has yet to emerge.
However, the analysis techniques on stochastic simulations of reaction networks are still underdeveloped in comparison to the rich arsenal of differential equation analysis techniques that have their roots in Newton's physics.
Second, there was the reaction of the newly independent underdeveloped countries against their past "colonial economic pattern," which they identified with free trade and primary production for the export market.
The underdeveloped Soviet road network, in a chain reaction, led to a growing demand for public transport.
Humans living in too-clean environments (or having fallen out of touch with old friends, meaning microbes), so the theories go, may end up with an underdeveloped immune system — in turn leading to severe allergic reactions or immune disorders later in life.
Alternatives to SMARTS-based molecular querying include Sybyl Line Notation (SLN) [9, 10], which itself is an adaption of SMILES, the relatively underdeveloped Molecular Query Language (MQL) [11], and the XML-based Chemical SubgReactions Reactions Markup Language (CSRML) [12].
However, analogous reactions that result in three-carbon annulation are currently underdeveloped,[ 6] and addressing this shortcoming would expand the range of products accessible using C H functionalization/oxidative annulation chemistry.
Despite considerable research in the area of allylic substitution, reactions using aryl nucleophiles to prepare all-carbon quaternary centers remain underdeveloped yet valuable.
When the reaction time was prolonged to 6 h, besides flower-like hollow architectures, some underdeveloped flower-like hollow architectures also existed in the as-synthesized samples, as shown in Fig. 3b, indicating that oriented attachment is still underway.
In general, my reaction to Norway's lenient, rehabilitation-focused justice system is not that the Norwegian sense of retributive justice is underdeveloped and defective, but that America's is.
