DOI: 10.1021/acsomega.2c07381
Abstract: The conjugated bis-guanidinate-stabilized zinc hydride complex (I)-precatalyzed chemoselective dehydroborylation of a wide array of terminal alkynes with excellent yields is reported. Further, precatalyst I is compared with a newly synthesized DiethylNacNac zinc hydride precatalyst (III)… read more here.
