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.

CpTiCl2, prepared in situ by manganese reduction of CpTiCl3, is an excellent new system for the Barbier-typeallylation and propargylation of carbonyl compounds. It can be used in catalytic amounts when combined with Et3N·HBr/TMSBr, which acts as a regenerating system. The high regio- and stereoselectivity shown by this system makes it useful for prenylation and crotylation processes in the synthesis

For the first time, the influence of surfactants on the radical pinacolcoupling reaction is investigated. The rate and selectivity of this reductive C‐C coupling are compared under three different activationtechnologies: thermal activation, microwave irradiation, and sonication. The use of IgepalCO520, a neutral surfactant, led to the successful conversion of aromatic or α,β‐unsaturated aliphatic

synthesis. Biocatalytic reduction of benzils is a straightforward approach to prepare these molecules. However, known methods are not selective and lead to formation of a mixture of benzoin and hydrobenzoin, requiring expensive separation procedures. Here, we describe an enzyme system Talaromyces flavus, which exhibited excellent pH dependent selectivity for the conversion of benzil to either benzoin or
