Abstract
- The syntheses and crystal structures of pentacyclo[9.4.1.0<superscript>5,14</superscript>.0<superscript>7,13</superscript>.0<superscript>12,15</superscript>]hexadecane-3,9-dione (2), a novel C<subscript>16</subscript> diketone with potential inclusion ability, and the products of the reaction of2 withn-butyllithium andmeso-erythritol (i.e.,meso-1,2,3,4-butanetetrol) are described. Crystal data:2·H<subscript>2</subscript>O, orthorhombic,Pmmn,a=10.7385(8),b=9.0188(6),c=6.8411(4)Å,V=662.55(7)Å<superscript>3</superscript>, andR=0.039 (379 reflections);3 (product from reaction withn-butyllithium), triclinic,P¯1,a=8.7192(7),b=10.9351(8),c=12.1842(8)Å,a=68.933(5),ß=75.850(6), ?=80.309(6)°,V=1047.0(1)Å<superscript>3</superscript>, andR=0.081 (1811 reflections);4 (product from reaction with erythritol), triclinic,P¯1,a=7.7224(8),b=10.1976(8),c=10.7021(9)Å,a=85.405(7),ß=85.766(8), ?=76.056(7)°,V=814.0(1)Å<superscript>3</superscript>, andR=0.052 (1471 reflections).
