  Ethyl-Branched Aldehydes, Ketones, and Diketones from Caimans (Caiman and Paleosuchus; Crocodylia, Reptilia)

  摘要：

  Secretions from the paracloacal glands of alligators (Alligator spp.) and caimans (Caiman spp., Melanosuchus niger, and Paleosuchus spp.) were examined by GC-MS. The secretions of the common caiman (C. crocodilus), the broadsnouted caiman (C. latirostris), the yacare caiman (C. yacare), the dwarf caiman (P. palpebrosus), and the smooth-fronted caiman (P. trigonatus) yielded a new family of 43 aliphatic carbonyl compounds that includes aldehydes, ketones, and beta-diketones with an ethyl branch adjacent to the carbonyl group. The identification of these glandular components and the syntheses and stereochemical investigations of selected compounds are described.

  The present invention is generally directed to organometallic compounds having Formula (I), Formula (II), or Formula (III) and devices having a layer including at least one of these compounds: (I), (II), (III) wherein: L1 is selected from an aryl-N-heterocycle ligand and a heteroaryl-N-heterocycle ligand , L2 is an anionic ligand , L3 is a nonionic ligand , L4 is selected from L1 and L2 M is a metal selected from Re, Ru, Os, Rh, Ir, Pd, Pt, and Au Fw is a moiety capable of bearing at least two (L4 -Ye) groups Y is a group selected from alkylene, heteroalkylene, alkenylene, heteroalkenylene, and alkynylene a is selected from 1and 2 b is selected from 0 and 1 c is selected from 0, 1, and 2 d is selected from 0 and an integer from 1 through 8 e is selected from 0 and 1 f is selected from 0 and 1 g is an integer from 1 through 4, and h is selected from 1and 2, with the proviso that a, b, and c are selected such that the metal is tetracoordinate when M is Au, Pd, or Pt, and the metal is hexacoordinate when M is Re, Ru, Os, Rh, or Ir, and with the proviso that when f = 0, then e = 0 and there is at least one substituent R1 on at least one ligand, wherein R1 is solvent-solubilizing. .
