One reaction to prepare these compounds adds diazomethylphosphonate esters to aldehydes under basic catalysis and generates vinyl-diazo intermediates. Along with aldehydes, these compounds are the degradation products of alpha, beta-epoxy tosylhydrazones in the Eschenmoser fragmentation. A coupling involving both palladium and copper catalysis, in which these compounds react with aryl halides, is the Sonogashira reaction. These compounds react with azides to form triazole rings in a well-known click-chemistry reaction, and terminal ones can be deprotonated by sodium amide. They are reduced to cis-alkenes by the poisoned Lindlar catalyst. This functional group is composed of two sp-hybridized carbons. For 10 points, name this functional group consisting of a carbon-carbon triple bond.

In one myth this deity laid the egg that would become the world and his association with the equinoxes led to his epithet as the god of balance. His center of worship was at Khmunu and one of his wives, Seshat, was the inventor of writing. He carried the eye of Ra in his role as messenger, but is better known for weighing the hearts of the deceased in his role as judge of the dead. Often depicted as a baboon, he hid Horus from Set after the latter killed Osiris and returned Tefnut to Ra's fold. FTP name this Egyptian god of scribes, wisdom, and the moon, most commonly depicted with the head of an ibis.

This thinker is famous for his writings on the concept of the "naturalistic fallacy" within the context of ethical systems. Editor of the periodical Mind, he began teaching in 1911 as a follower of Kant's transcendental epistemology, and went on to expound on the need to carefully clarify and examine the meaning of propositions while championing common sense. The author of Refutation of Idealism and major influence on the Bloomsbury Group, FTP, who was this major British philosopher, the author of Principia Ethica
