An efficient method was developed for the protection of alcohols as trityl ethers using triphenylmethanol in the presence of nanoporous MCM-41-SO3H as a heterogeneous catalyst under solvent-free ball-milling at room temperature. Low catalyst loading, high efficiency, reusability are among the advantages of this new solvent-free and environmentally friendly method. The deprotection of the produced trityl ethers was also efficiently achieved using the same catalyst in wet acetonitrile.
N, N′ - Ditritylurea and analogs as hosts in crystalline clathrate complexes: Synthesis and selectivity studies

Of 38 hosts, most of them new, designed on the 'wheel-and-axle' model, 24 formed clathrate complexes with small molecules; 95 new host/guest combinations are described (Table 6). Selectivity studies (Table 7) show, in some instances, substantial discrimin
