	JCE 2002 (79) 678 [Jun] Functional Group Chemistry (by James R. Hanson)
		The remaining three divide functional groups into three broad classes: those whose reactivity is in the sigma bonding framework, those containing pi bonds, and those containing aromatic rings.
		Chapter 1 begins by discussing the factors that give rise to the structure of functional groups; it moves on to the interrelationship between functional groups; and it ends with an overview of reaction types.
		He first introduces a functional group, next provides methods by which it is formed, and finally demonstrates reactions in which it is involved.

	DNA Adducts and Carcinogenicity of Nitro-polycyclic Aromatic Hydrocarbons
		The nitro group is a highly electronegative functional group and its presence to a PAH molecule increases the molecular size.
		Nitro orientation has been demonstrated to be an important structural feature in determining the metabolism pattern, bacterial mutagenicity, DNA binding, and tumorigenicity of nitro-PAHs, which exhibit mutagenicity drastically different from their parent PAHs.
		When a nitro group is introduced to a carcinogenic bay-region containing PAH and the nitro group of the resulting nitro-PAH preferentially adopts a perpendicular or nearly perpendicular orientation, the tumorigenicity of this nitro-PAH is weaker than the parent PAH.

	Yellow couplers having an arloxy coupling-off group which contains an ortho polarizable functional group - US Patent ... (Site not responding. Last check: 2007-10-14)
		The novel couplers include (a) an acyl acetanilide in which the acyl group has a monocyclic or multicyclic carbon center attached to the carbonyl moiety, and (b) an aryloxy coupling-off group at the coupling position of the acylacetanilide, the coupling-off group having in the ortho position a polarizable substituent.
		However, while the SDP coupling-off group successfully enhances the coupling efficiency of the pivaloylacetanilide-class yellow couplers, it enhances coupling efficiency to a lesser extent when employed with two important new classes of yellow couplers, the 5-alkyl-1,3-dioxanoylacetanilide-class and the adamantoylacetanilide-class couplers, which are disclosed, for example, in U.S. Pat.

		This work presents the chemistry of functional groups with an emphasis on patterns of reactivity, the consequences of the relative electronegativity of the atoms that constitute the functional groups, the role or lone pairs and the stereochemistry of reactions at a particular group.The material is presented in four sections.
		The third section covers symmetrical p-bonded functional groups including alkenes, alkynes and arenes and the consequences of the factors that perturb the symmetry, such as on the orientation of aromatic substitution.
		The final section concentrates on interconversions like oxidation and reduction, and the protection of functional groups to achieve selectivity.The chemistry of the functional groups is considered here with mechanistic rationale.

		Unlike the nitro group which contained functional groups we will not be discussing, the carboxyl group is made up of a resonance hybrid between a carbon oxygen single bond and a carbon oxygen double bond.
		In the cases of the nitro group and the carboxylate anion, both resonance forms contribute equally to describing the ground state of the molecule.

	The Chemistry of Nitrogen Compounds
		Nitroso groups are strongly electron withdrawing, like the nitro group, but the situation is complicated by the dimerisation reaction.
		As the nitrosyl group is strongly electron withdrawing and more similar to the C=O than the NO group There is polarisation of the N=O bond and so behaves as a weak C=O. It undergoes addition of nucleophiles and condensation with primary amines and the anions of active methylene compounds, e.g malonates, b ketoesters;
		A group of similar reactions involve the migration of an alkyl group, R, from carbon to electron deficient nitrogen, the nitrene or nitrenium ion.

		According to FSU, the sum total of Tao's knowledge and experience with taxol and taxanes was gained at FSU in Holton's laboratory, and Tao's work at ABI was simply a continuation of scientific investigations begun by the Holton group at FSU.
		FSU's strongest arguments for Holton's being a coinventor of the three claimed compounds are that (1) "[t]he sum total of Tao's knowledge and experience with taxol and taxanes was gained in the laboratories of FSU as a member of the Holton research team"; (2) "Tao's.
		The district court held that Yang was a coinventor of the compounds claimed in the '653 patent on the basis of Tao's having had knowledge of Yang's discovery that PNIP was the best dual functional radiosensitizer among the taxol analogs that Holton provided to him to test.
