Reduction of (CAAC)BBr (NCS) (CAAC=cyclic alkyl(amino)carbene) in the presence of a Lewis base L yields tricoordinate (CAAC)LB(NCS) borylenes which undergo reversible E/Z-isomerization. The same reduction in the absence of L yields deep blue, bis(CAAC)-stabilized, boron-doped, aromatic thiazolothiazoles resulting from the dimerization of dicoordinate (CAAC)B(NCS) borylene intermediates.
在路易斯碱L存在的情况下还原(CAAC)BBr (NCS)（CAAC = 环状烷基（氨基）卡宾）会生成三配位的(CAAC)LB(NCS)硼烯，该硼烯会发生可逆的E/Z异构化。在没有L的情况下进行相同的还原反应会生成深蓝色的、由双（CAAC）稳定的、硼掺杂的芳香族噻唑并噻唑，这是由二配位的(CAAC)B(NCS)硼烯中间体二聚而成的。
