Carborane-Based Pincers: Synthesis and Structure of SeBSe and SBS Pd(II) Complexes
摘要:
We report the synthesis of several unique, boron-rich pincer complexes derived from m-carborane. The SeBSe and SBS pincer ligands can be synthesized via two independent synthetic routes and are metalated with Pd(II). These structures represent unique coordinating motifs, each with a Pd-B(2) bond chelated by two thio- or selenoether ligands. This class of structures serves as the first example of boron-metal pincer complexes and possesses several interesting electronic properties imposed by the m-carborane cage.

7-bis[chloro(dimethyl)silylmethyl]-m-carborane using 1-haloidmagnesiummethyl-m-carborane and 1,7-bis[haloidmagnesiummethyl]-m-carborane was developed. It has been established that in the course of the reaction of 1-haloidmethyl-m-carboranes with magnesium both in ether and THF, simultaneously with the formation of 1-haloidmagnesiummethyl-m-carborane – the resulting Grignard reagent, proceeds the isomerization
