Reaction-pathway control of benzo[b]thiophen-3-yllithium and benzo[b]furan-3-yllithium was accomplished in flow microreactor systems. We could switch between the reaction with an electrophile before ring-opening and that after ring-opening at will by choosing an appropriate residence-time and temperature.

A metal-free CH-CH-type coupling of arenes and alkynes, mediated by a multifunctional sulfoxide directing group, exploits nonprefunctionalized coupling partners, proceeds under mild conditions, is operationally simple, and exhibits high functional group t

An effective method for the synthesis of photochromic diarylethenes through the generation of heteroaryllithiums and subsequent reaction with octafluorocyclopentene has been developed by using integrated flow microreactor systems. Reactions can be conducted without using cryogenic conditions by virtue of effective temperature and residence time control, although much lower temperatures (-1. Therefore, the present integrated flow microreactor method serves as a practical way of synthesizing various photochromic diarylethene derivatives. Too successful to be cool: An effective method for the synthesis of photochromic diarylethenes has been developed by using integrated flow microreactor systems. Reactions can be conducted without the need for cryogenic conditions by using these systems (see picture). The synthesis of unsymmetrical diarylethenes, which is difficult to achieve by using conventional macro batch systems, has also been accomplished. Copyright

Access to the title compounds (12-14) was achieved by two different syntheses starting from either phenylacetylene (1) or, from benzothiophene (2) by a reaction sequence formally equivalent to the insertion of sulfur.The key intermediates in both route
A NEW SYNTHESIS OF 2-SUBSTITUTED BENZOFURANS AND BENZOTHIOPHENS: NOVEL FRAGMENTATION REACTIONS OF SIMPLE ALKYL GROUPS
Aitken, R. Alan,Burns, Graham
, p. 3717 - 3718 (2007/10/02)
Flash vacuum pyrolysis of (2-methoxy- and (2-methylthiobenzoyl)alkylidenetriphenylphosphoranes results in loss of Ph3PO and methyl radical; cyclisation of the resulting radical intermediates leads to benzofurans and benzothiophens in which the 2-substituents have undergone novel fragmentation processes.
