This review summarizes the Pd-catalyzed cyclization of an allene bearing a nucleophilic functionality with an organic or inorganic halide, and the cyclization involving two allene moieties or an allene–alkene, allene–1,3-diene, allene–alkyne, allene–aldehyde, or allene–ketone combination in the presence or absence of an organic halide. The cyclic compounds were formed highly selectively via (1) intermolecular...

In this paper, we introduce a wide-range, accurate LDPC coded-aided frequency offset compensation algorithm based on both EM algorithm and M&M algorithm in space coherent optical communication systems. The proposed approach can overcome the shortcoming of the existing frequency offset compensation algorithms which are employed in space coherent optical communication systems directly. It allows...
