TL;DR: In this paper, the stereoselective allylindation of methylenecyclopropanes carrying a hydroxymethyl group at the ring of the ring has been studied, where the allyl group was delivered at the external sp 2 carbon via cyclopropylindium intermediates.

TL;DR: In this paper, the stereoselective allylindation of methylenecyclopropanes carrying a hydroxymethyl group at the ring of the ring has been studied, where the allyl group was delivered at the external sp 2 carbon via cyclopropylindium intermediates.
Abstract: Methylenecyclopropanes carrying a hydroxymethyl group at the ring underwent stereoselective allylindation with allylindium sesquiiodide to afford the allylated products, in which the allyl group was delivered at the external sp 2 carbon via cyclopropylindium intermediates. The reaction of ethyl 2-cyclopropylideneacetate and triallylindium afforded the 1,4-adduct along with dimeric products.

TL;DR: In this paper , the authors demonstrated electrical control of the repetition frequency and offset frequency of RTD terahertz oscillators by bias voltage modulation, which can pave the way for the realization of a stabilized frequency comb using RTD oscillators that operate at room-temperature.
Abstract: We experimentally demonstrated electrical control of the repetition frequency and offset frequency of mode-locked resonant tunneling diode (RTD) terahertz oscillators by bias voltage modulation. These results will pave the way for the realization of stabilized terahertz frequency comb using RTD oscillators that operate at room-temperature.

TL;DR: In this article, the three principal methods to synthesize these important compounds are based on the formation of the cyclopropane ring, the use of preformed cycloprocessors, and the preformed methylene- and alkylidenecyclopropanes.
Abstract: Since the methylenecyclopropane moiety is found in many biologically active natural substances, the synthesis of methylene- and alkylidenecyclopropanes remains a considerable challenge. In addition, an attractive feature is their surprising stability, accompanied by a high level of strain, conferring on them an otherwise unattainable chemical reactivity. The growing interest in the chemistry of these compounds has in its turn stimulated the development of alternative approaches to their skeleton, aimed at selectively introducing structural and chemical diversification. The three principal methods to synthesize these important compounds are based on the formation of the cyclopropane ring, the use of preformed cyclopropanes, and the use of preformed methylene- and alkylidenecyclopropanes.

TL;DR: Methylenecyclopropanes (MCPs) are highly strained but readily accessible molecules, and their high ring strain provides them with increased reactivity, and MCPs undergo a series of interesting reaction as discussed by the authors.
