The utility of 2-diphenylphosphoryloxy-1,3-dienes for the construction of substituted six-membered nitrogen heterocycles is presented. These dienes undergo boron trifluoride-promoted aza-Diels-Alder reactions when reacted with imines or related speci

A pedagogical technique, named the Bridge activity, has been developed to assist students’ transition from preclass preparation to in-class learning within a flipped organic chemistry course. Bridge activities form the basis of an initial interacti

These studies provide the first evidence for styrene–phosphaalkene connectivities in a phosphaalkene copolymer. The synthesis and structural characterization of new phosphaalkene–oxazolines, ArP═C(Ph)(3-C6H4Ox) [1a,b, Ar = Mes (1a), Mes* (1b),

Demands are placed on undergraduate courses in chemistry to develop transferable skills, such as teamwork, alongside subject content and technical skills. Such skills can be developed by implementing pedagogies which involve students working together

The addition of alkyl nucleophiles (MeM, M = Li, MgBr) across the P═C bond of an enantiomerically pure phosphaalkene-oxazoline followed by protonation of the C anion affords phosphines with three chirality centers. The formation of palladium(II) co

Substituted tetrahydroxanthones are constructed using a DMAP-promoted tandem nucleophilic addition process. The reaction yields range from 39% to 73%. Disubstituted tetrahydroxanthones are generated as a ∼2.3:1 mixture of diastereomers favoring the

Polyamines are ubiquitous organic cations implicated in many physiological processes. Because they are positively charged at physiological pH, carrier-mediated systems are necessary for effective membrane permeation, but the identity of specific poly

The synthesis of enantiomerically pure pyridine-bridged phosphaalkene-oxazolines ArP═C(Ph)(2,6-C5H3NOx) (1, Ar = Mes/Mes*, Ox = CNOCH(i-Pr)CH2/CNOCH(CH2Ph)CH2) is reported. This new ligand forms a κ(P), κ(2)(NN) dimeric complex with copper(I) (7)

The radical-initiated copolymerization of phosphaalkene-oxazoline, MesP[double bond, length as m-dash]C(Ph)CMe2Ox [1, Ox = CNOCH(iPr)CH2] with different loadings of styrene affords poly(methylenephosphine-co-styrene)s [2a (1 : S = 1 : 2): Mw = 7400 g
