The next addition reaction
proceeds smoothly by the attack of a nucleophile, in this case, 6-hydroxy group, leading to the formation of 1,6-anhydro skeleton.
Therefore, we showed the diastereoselective synthesis of S,S-2-methylsulfanyl-2-methylsulfinyl-1indanol (7) by reduction reaction using 2-methylsulfanyl-2-methylsulfinyl-1-indanone (9) optically enriched demonstrating the high efficiency of the sulfoxide group on the control of asymmetric induction in the carbonyl addition reaction
2] as a catalyst without adding any bromoform, only isomerized product was formed with no addition reaction
taking place in all three methods.
After the Michael addition reaction
was complete as demonstrated by NMR, polyesterification was performed by increasing the reaction temperature to 120[degrees]C, adding 0.
Addition polymerization is the formation of polymers from monomers containing a carbon-carbon double bond through an exothermic addition reaction
Ammonium chloride which is inexpensive and readily available reagent catalyzes the thia-michael addition reaction
of thiols in water efficiently.
2] group and the active hydrogen atoms of these functional groups may lake part in the polymerization of BMI with BTA via the Michael addition reaction
Our preliminary studies indicate the addition reaction
taking place initially at room temperature followed by rotation, isomerization and elimination at higher temperatures.
Hydrosilylation, which is the addition reaction
of a hydride terminated silane compound to a multiple bond , has been recently investigated as a possible method for polymer functionalization in solution .
The three new adhesive types are two-component, colorless and transparent silicone gels that crosslink via a platinum-catalyzed addition reaction
to form soft, highly flexible materials with an elastic, gel-like consistency.
It is miscible in xylene with the PDMS containing vinyl group of 10 mol% and the HSO to prepare easily the CHM by silicon-hydrogen addition reaction
at room temperature by means of casting solution method.
Both compounds yielded the same product, triflate 6 by addition reaction
while the sulfonyl 8 by addition- elimination reaction (Scheme-2).
The new products are solvent-free and cure by a platinum-catalyzed addition reaction
With the reactive bismaleimide groups (two terminal -C=C-groups), BMI can polymerize with active hydrogen atom-containing species such as polyamines via the Michael addition reaction
Terminal, or pendant double bonds (vinyl), have low steric hindrance and are more likely to participate in addition reaction
than internal double bonds (cis/trans).
