In this paper, we analyze the influencing factors of the customer loyalty and set up the relational assess model, then apply analytic hierarchy process to establish the relation weights which influence the customer loyalty. At last, by means of applied instances in telecommunication industry, we represent the internal relations between the influencing factor weights and the customer loyalty and put forward marketing strategies on product and customer divergences to develop the customer loyalty.

An extremely efficient acylative kineticresolution of d,l‐1,2‐diols in the presence of only 0.5 mol% of binaphthyl‐based chiral N,N‐4‐dimethylaminopyridine was developed (selectivityfactor of up to 180). Several key experiments revealed that hydrogen bonding between the tert‐alcohol unit(s) of the catalyst and the 1,2‐diol unit of the substrate is critical for accelerating the rate of monoacylation

Reported herein is the asymmetricpinacolcoupling of aromatic aldehydes with chiral Salan−Mo(VI) dioxo complex as an effective precatalyst. Chiral diols were obtained with high diastereoselectivity and enantioselectivity up to 92/8 and 95%, respectively. The possible mechanism of the pinacolcoupling reaction with the catalytic system was investigated. The X-ray crystal structure of the precatalyst
