Visible-Light-Promoted Transition-Metal-Free Phosphinylation of Heteroaryl Halides in the Presence of Potassium tert-Butoxide

A novel visible-light-promoted C-P bond formation reaction in the absence of both transition metal and photoredox catalysts is disclosed. By employing easily available and inexpensive heteroaryl chlorides/bromides as substrates, a variety of heteroaryl phosphine oxides were obtained in moderate to good yields. This strategy provides a simple and efficient route to heteroaryl phosphine oxides.

Synthesis of Some Potential Antihypertensive Phthalazinyl- and Quinoxalinylguanidines

A series of phthalazinyl- and quinoxalinylguanidines has been synthesized and evaluated for potential antihypertensive activity.Unsubstituted guanidines were prepared by treating the appropriate intermediate chloro compounds with guanidine free base.Substituted guanidines were prepared by treating the cyanamides 9 and 16 with the appropriate amine; with hydrazines, cyanamide 9 gave the triazoles 14 and 15.Moderate falls in blood pressure were observed with compounds 10, 11, 14, and 15.The triazole 15 caused a 25percent fall in heart rate.Some of the compounds (10, 11, 13, and 18) displayed weak alpha-adrenoceptor antagonist properties in vitro, and this activity was confirmed in the pithed rat (in vivo).
