Isopropyl ethenyl

Vilsmeier-Haack formylation of 2-(4-methyl-l-piperazinyl)-4//-pyrido-[l,2-n]pyrimidin-4-one with a mixture of POCI3 and DMF at 95°C gave a 3-formyl derivative (93FES1225) while ethyl 4-oxo-6,7,8, 9-tetrahydro-4//-pyrido[l,2-n]pyrimidine-2-acetate at 50 °C yielded a 9-dimethylaminomethylene-3-formyl derivative (01MI4). 3-Formyl-2-hydroxy-8-[2-(4-isopropyl-l,3-thiazol-2-yl)-l-ethenyl]-4//-pyrido[l,2-n]pyri-midin-4-one was obtained from the 3-unsubstituted derivative with oxalyl chloride-DMF reagent in CH2CI2 at room temperature for 3h (OlMIPl). 

Comparison of groups such as isopropyl and ethenyl is more difficult and requires knowing what the convention is when we have to go to the far end of a double bond. A useful way of writing these groups is as follows ... 

We put ethenyl ahead of isopropyl because [(C), H, H] takes priority over (H, H, H). It is important to understand that the nonduplicated carbon is considered to be connected to the duplicated carbon as well as the two hydrogens in arriving at the connection pattern ((C), H, H).

Solubility determinations were used to characterize the polymorphism of 3-(((3-(2-(7-chloro-2-quinolinyl)-( )-ethenyl)-phenyl)-((3-dimethylamino-3-oxopropyl)-thio)-methyl)-thio)-propanoic acid. " The solubility of Form II was found to be higher than that of Form I in both isopropyl alcohol (IPA, solubility ratio equal to 1.7 over the range of 5-55°C) and methyl ethyl ketone (MEK, solubility ratio equal to 1.9 over the range of 5-55°C), indicating that Form I is the thermodynamically... 

Pyrolysis of poly(4-vinyl pyridine) was demonstrated to be a free radical process. Both poly(vinyl pyridines) generate as a main pyrolysis product the monomer, 2-ethenylpyridine or 4-ethenylpyridine, respectively. In the pyrogram of poly(2-vinyl pyridine), the dimer is also present (30% of the peak area). This peak is not seen in the pyrogram of poly(4-vinyl pyridine), but it is possible that the compound exists and elutes at a longer retention time than the one used in the chromatographic conditions applied for the pyrolysate separation. Other pyrolysate components not shown in Table 6.5.11 or 6.5.13 were reported in literature. Among these are propenylpyridine, isopropyl-pyridine, isoquinoline, phenylpyridine, 4,4 -dipyridyl, 4-[2-(4-pyridyl)ethyl]pyridine, 4-[2-(4-pyridyl)ethenyl]pyridine, 4-[3-(4-pyridyl)propyl]pyridine, etc. [39]. Similarly to the case of polystyrene, the H-T polymerization is prevalent in poly(vinylpyridine). However, some H-H units can be present in the polymer, and their abundance can be estimated from Py-GC/MS data.
