1 Source of material

1,8-Diiodoanthracene (430 mg, 1 mmol) was placed in a 50-ml Schlenk flask along 4,4 ′ -(adamantane-1,3-diyl)diphenol (320 mg, 1 mmol), methyl 2-bromoacetate (334 mg, 2.2 mmol) and Na2CO3 (552 mg, 4.0 mmol) were placed in a 50-ml Schlenk flask along with 30 ml CH3CN. The reaction was stirred in the dark at 60 °C for 2 days. The solvent was removed in vacuo; the residue was dissolved in dichloromethane, washed with water, and then washed with brine. The organic fraction was dried with Na2SO4, filtered through a silica gel plug, and the solvent was removed on a rotary evaporator to produce the title product (441 mg, 0.95 mmol) as a white solid. Crystals were obtained by slow vapor of solution of title compound in CH2Cl2 within 1 week.

2 Experimental details

Hydrogen atoms were placed in their geometrically idealized positions and constrained to ride on their parent atoms.

3 Comment

Adamantane is one of the most stable hydrocarbons [3], [4], [5]. This high degree of stability is due to its arrangement of four cyclohexane rings fused with each in the favorable chair conformation. Moreover, adamantane has a highly symmetrical structure with nearly spherical molecules that can be packed tightly into a lattice and easily crystallized in common organic solvents. Self-assembled adamantanoids were first introduced by Saalfrank and co-workers [6], [7], [8]. Zeng and co-works reported the preparation of polymeric hydrogen-bonded supramolecules by self-assembling of adamantane derivatives with bipyridines [9]. Richert’s group reported that tetrakis(dimethoxyphenyl)adamantane can act as a protective crystalline coat for reagents, enabling the formulation of reactive, malodorous, or toxic compounds [10]. Very recently, we reported the use of 4,4 ′ -(adamantane-1,3-diyl)diphenol as a non-porous adaptive crystal to separate benzene from mixed vapors of cyclohexane and BTX under conditions of room temperature and atmospheric pressure [11]. Herein, as continue work, we reported the synthesis of dimethyl 2,2 ′ -((adamantane-1,3-diylbis(4,1-phenylene))bis(oxy))diacetate. The title compound, built up by the C28H32O6 molecules. In the title crystal structure the molecules are located on a mirror plane. The single-crystal structure verifies that all bond lengths are in normal ranges [12, 13].
