Application

sec-Butyllithium solution (1.4M in cyclohexane) has been used in the multi-step synthesis of 5-methyl-5,6-dihydrothymidine (5-MDHT) from thymidine. It has also been used in the copper-catalyzed asymmetric allylic alkylation (AAA) of allyl bromides, chlorides, and ethers in the presence of a chiral ligand.

Packaging

The 25 mL Sure/Seal™ bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.

A series of 6,6-dihalo-2-azabicyclo[3.1.0]hexane and 7,7-dihalo-2-azabicyclo[4.1.0]heptane compounds were prepared by the reaction of dihalocarbene species with N-Boc-2,3-dihydro-1H-pyrroles or -1,2,3,4-tetrahydropyridines. Monochloro substrates were synthesised as well, using a chlorine-to-lithium exchange reaction. The behaviour of several aldehydes and ketones under reductive amination

Although living polymerization methods are widely applicable to organic monomers, their application to inorganic monomers is rare. For the first time, we show that the living poly(methylenephosphine) (PMPn- ) anion can function as a macroinitiator for olefins. Specifically, the phosphaalkene
