Catalytic Performance of Heteropoly Acids on Different Supports in the Synthesis of Dihydropyrimidones

For such a node at a coarse scale, the nodes into which it decomposes at the sub metamer scale of the XEG are used to compute a bounding box or a convex hull of a type that extends

The Big- inelli reaction is the most straightforward and simple protocol for the synthesis of DHPMs, and involves a one-pot, but low-yield (25 – 60 %) condensation of β

The structure of the cluster with 64 CVE is that of a “spiked triangle” in which the triphenylphosphonioacetylide CCPPh 3 acts as a six-electron donor and the bonding mode is that of

The difference between the P–C distances to C(5) and to the phenyl carbon atoms amounts to about 10 pm, and the shorter bond lengths to the ylidic carbon atom indicate some double

The polymerization behavior of catalysts 8a – d in toluene solution (Table 1: Run 1 – 18) comprises mod- erate catalyst activities at 30 ◦ C with no significant variation concerning

In both cases, dimers are present on the surface and arrange side-by-side to form stripes, however, when depositing the dimers directly, the stripes are predominantly aligned along

A historical overview of the development of functional imaging is followed by the portrayal of the principles and applications of positron emission tomography (PET) and
