A derivative of this compound with three methyl and carboxyl groups is used for molecular recognition studies and readily coordinates the uranyl ion. Three equivalents of this molecule are bonded to phosphorus to form a ligand with a 170-degree (-5[1])cone angle (-5[2])that is found in both (-5[1])Crabtree’s (-5[1])and Grubbs’ (-5[1])catalysts. (-5[1])1.74 (-5[1])kilocalories-per-mole (-5[1])is assigned to methyl under the (-5[1])(*) A-value scale used to assess (10[1]-5[1])the stability (10[2])of (10[1])this molecule’s (10[1])derivatives. (-5[1])Two (10[1])doubly-linked (10[1])Newman projections (10[1])may be used to visualize (10[1]-5[2])unfavorable flagpole interactions (10[2]-5[1])that (10[1])destabilize (10[2])this molecule’s (10[1])boat conformation, (10[8]-5[3])causing (10[1])its (10[1])chair (10[1])conformation (10[1]-5[1])to be (-5[1])favored. (-5[2])This compound is industrially (10[1])produced by using Raney nickel to hydrogenate benzene. (10[3])For 10 (10[1])points, name this cyclic (10[3])alkane (10[1])with the formula C6H12.
